１，安福寺漆棺片より剥落した試料片についてAMS分析法による¹⁴C年代測定を行い，漆棺が6世紀後半から7世紀中頃に制作された可能性が高いことを示した。その結果，同漆棺片を叡福寺北古墳(宮内庁が管理する磯長墓)より出土した棺の一部とする従来の説と矛盾しない年代に納まった。
２，漆棺より剥落した塗膜の断面を顕微鏡観察し，漆棺の制作技法を検討した。その結果，安福寺漆棺片の胎が絹布層と火山灰を主材料とする地粉層を交互に塗り重ねた構造からなること，絹布の織りは均一でなく，繊維断面の形状も一定せず，絁の可能性が高いことを明らかにした。
３，棺台ならびに漆棺の法量が明らかな阿武山古墳出土漆棺(終末期古墳)，法隆寺五重塔初層西面金棺における棺台長と棺身長の比率の比較をもとに，磯長墓棺台に載る漆棺の法量を推定した。その結果，阿武山古墳漆棺における幅/長さ比をもとにすると，磯長墓棺の推定棺蓋長は217.8㎝，同様に棺身長は210㎝，棺身幅は83.2㎝となった。次に，法隆寺五重塔初層西面における金棺の法量比を同様にして当てはめると，棺蓋長は196㎝，棺身長は193.6㎝，棺身幅は60.2㎝となった。最後に，安福寺漆棺片の棺身長を，既知もしくは記録により棺身長と棺幅長を推定できる漆棺の幅/長さ比と比較した。その結果，安福寺漆棺片を仮に短辺と考えると，長辺が３メートル近くに復元され，既知の棺台に載らず，漆棺の長辺の一部と考察するのが妥当であるとの結論に至った。, I investigated on the lacquer coffin fragment belonging to Anpukuji Temple of Kashiwara-shi, Osaka-fu, in this study. Through an AMS (Accelerator Mass Spectrometry) analysis method, I performed carbon-14 dating on a sample fragment that had peeled off from the Anpukuji Temple’s lacquer coffin fragment and found that it was highly possible that the lacquer coffin was made between the late 6th Century and the middle of the 7th Century. The resulting time period does not contradict the hitherto viewpoint that this lacquer coffin fragment was a part of the coffin excavated from the Eifukuji Temple Kita Kofun (a Shinaga grave managed by the Imperial Household Agency). Further, I observed a section of the coating film that had peeled off from the lacquer coffin through a microscope and assessed its production technique; consequently, I noted that the material of the Anpukuji Temple’s lacquer coffin fragment was made up of a structure created by painting layers upon layers, alternating between silk cloth and soil powder that contained volcanic ash as the main ingredient. I noted that the fabric of the silk cloth is uneven and the shape of the fiber section is not fixed, thus concluding that this fragment is ashiginu (a cloth woven with thick thread). I estimated the measurements of the lacquer coffin that would go on the Shinaga grave coffin platform on the basis of comparisons with the coffin’s length to coffin’s platform length ratio of the lacquer coffin excavated from the Abuyama Kofun (Shuumatsuki Kofun) and the golden coffin from the first layer on the west side of the Horyuji Temple Five-story Pagoda, whose coffin’s length and coffin’s platform length are known. Thus, using the width/length ratio of the lacquer coffin of the Abuyama Kofun as the basis, the estimated coffin lid length of the Shinaga grave coffin was 217. 8 cm, the coffin length was 210 cm, and the width was 83.2 cm. Next, using the measurement ratio of the golden coffin in the west first layer of the Horyuji Temple Five-Story Pagoda, the estimated coffin lid length was 196 cm, the coffin length was 193.6 cm, and the coffin width was 60.2 cm. Finally, I compared the coffin length of the Anpukuji Temple lacquer coffin fragment to the width/length ratio of lacquer coffins for which I could estimate coffin lengths and widths through existing knowledge or records. As a result, if we think of the Anpukuji Temple lacquer coffin fragment as being a part of the shorter side, the longer side would be reconstructed as nearly 3 m long, and the coffin would not fit on the known coffin platform. Therefore, I deduced that the fragment can be considered as a part of the longer side of the lacquer coffin.},
