The purpose of this study is to compare the relationship between the calibrated ^<14>C age and the historical age of Japanese paper samples. Calibrated ages of nine pieces agree with their historical ages, indicating that ancient Japanese documents of the recent historic period can be suitable for ^<14>C dating analysis. On the other hand, the ^<14>C age of a paper fragment that was used for reinforcement of a sutra is about 300 years older than the historical age of the sutra. This suggests that an old sheet of paper, instead of new one, was used in the ancient repair of this sutra., タンデトロン加速器質量分析計業績報告 Summaries of Researches Using AMS 1997 (平成9)年度}, pages = {324--334}, title = {名古屋大学タンデトロン加速器質量分析計による古文書資料の ^<14>C年代測定}, volume = {9}, year = {1998} }
