 note = {(１)　銅鋺の型式分類と編年は，毛利光俊彦・桃崎祐輔によって大綱が確立されている。本稿は，古代前期の食器制を特徴づける金属器示向の原点とされてきた銅鋺の器形・加飾による分類・編年の再構成を意図する。そのため，まず全国の事例を悉皆的に収集し，法量分化と各部位の指数化によるデータの客観性を高めようとした。また，銅鋺の初現年代と系譜の検討を通して，銅鋺の史的意義に迫る予備的作業を行った。
銅鋺は１０類に分類したが，大半は倭国独自のＡⅠ・Ⅱ類高脚・台脚杯と，韓半島の食器で一般的なＢⅠ類高足鋺，Ｃ・Ｄ類無蓋無台鋺が占める。これらは，基本的に酒杯＋飯鋺に陶製の酒瓶の宴器セットを表徴し，倭王権の外交権を示威する威信財と考える。酒杯・飯鋺は配付する首長による格付けがあり，７世紀中葉（大化）前後で器形・加飾が大きく変化し，配布対象も下位層に及ぶ。
(２)　銅鋺をモデルに各地で模倣土器が作られ，金属器示向が普及する。型式は一見多様だが，大阪・陶邑窯で定型化された情報が地方窯へ一元的に伝達されるシステムの存在が想定される。銅鋺同様ＡⅠ・Ⅱ類，ＢⅠ類タイプが７世紀中ころ消失するので，銅鋺に準ずる食器の階層化を意図したとみられる。
(３)　銅鋺の理化学分析（鉛同位体，蛍光Ｘ線分析）の成果と論点を要約した。課題が多いが，韓半島の銅・鉛原料に一部中国の原料を移入し，７世紀代を通して国産品が生産，配布されたと推測する。, (1) The type classification and chronology of copper bowls were established by Toshihiko Morimitsu and Yusuke Momozaki. The copper bowl, which is the subject of this paper, has been regarded as the starting point of the preference for metal utensils that characterized the tableware system of the early antiquity. This paper examines the reconstruction of the classification and chronology of copper bowls based on their vessel shape and decoration. For that purpose, we collected all the examples of copper bowls excavated from all over the country, and tried to increase the objectivity of the data by classifying the size and indexing each part. In addition, preliminary work was carried out to approach the evaluation of the historical significance of copper bowls. Copper bowls were classified into 10 categories. Most of them are made up of Wa Kingdom’s original type AI/II high-stand cup, and BI type of high stand bowl and C and D type lidless bowl, which are common in the Korean Peninsula. These are basically symbol of sake bottles made of pottery with the Sake cup + rice bowl, and are considered prestige goods that demonstrate the diplomatic power of the Wa Kingdom. The type and structure of sake cups and tea bowls differed depending on the ranking of the local chief within the W a Kingdom. In the middle of the 7th century (Taika), the shapes and decorations of the vessels changed greatly, and the target of distribution from the W a Kingdom also extended to the lower classes.
 (2) Earthenware imitating copper bowls was made in various places, and the preference for metalware spread. Although the types of imitation pottery seem to be diverse at first glance, it is assumed that there was a system in which the information that had been standardized at the Toyu kiln in Osaka was transmitted to the local kilns in an integrated manner. Similar to copper bowls, the AI/ II and BI types of imitation earthenware disappeared in the middle of the 7th century, suggesting that there was an intention to stratify tableware in the same way as copper bowls.
 (3) I summarized the results and points of discussion of physical and chemical analysis (lead isotopes, fluorescent X-ray analysis) of copper bowls. Although there are many problems, it is speculated that copper and lead as raw materials were imported from the Korean Peninsula and China, and copper bowls were produced in Wa Kingdom in the 7th century.},
