 note = {The difference of radiocarbon ages are examined for the charred materials between inside and outside pottery from a wetland archaeological site. The samples consist of 8 pieces of potsherds, which are excavated from Irienaiko archeological site, around the lake Biwa, Shiga prefecture and are found to be originated from the same pottery of the "Kitashirakawa-kasou IIc type" in the first half of the middle Jomon era. The AMS radiocarbon dating for these potsherds indicates that the inner surface of the potsherds (5053±12 BP; N=5) are about 90 ^<14>C year older than that of outer ones (4961±22 BP; N=7). The difference is likely to be caused by four cases as follows. 1) old wood effect, 2) marine reservoir effect, 3) freshwater reservoir effect, 4) diagenesis. In this paper, we discuss about the difference of radiocarbon ages found between inner and outer surface on potsherds.
