本稿は，19世紀の萩藩を中心として，米切手の偽造に対する刑罰と偽造事件を明らかにした。第1に，萩藩に限らず，地方市場では米切手の偽造問題が存在した。第2に，萩藩では，偽造米切手を担保金融に利用した事件が起きていた。広範囲で米切手が流通することは，偽造米切手が紛れ込む余地を与えた。しかし，米会所や米仲買が偽造発見と流通防止の役割を果たすことで，信用不安のような大問題に発展しなかったと考えられる。
This study discusses the punishment for counterfeiting rice bills and cases, focusing on the Hagi domain in the 19th century. First, the problem of counterfeit rice bills existed not only in the Hagi domain but also in the local market. Second, in certain instances, counterfeit rice bills were used as collateral finance in the Hagi domain. The wide circulation of rice bills provided room for counterfeit rice bills to be mixed up. However, the role of rice exchanges and rice brokers in detecting and preventing the circulation of counterfeit rice bills has prevented the occurrence of major problems, such as the credit crisis.
