The purpose of this paper is to report radiocarbon age for charred carbonaceous residue on the surface of deep bowls in the Late and Latest Jomon, which were found in Ishikawa Prefecture. Solid-carbon and Humic-acid ingredients were separated by using NaOH solutions from charred deposits, most likely the food residue of Jomon people, collected from the surface of seventeen pottry fragments. ^<14>C ages have been measured by using a Tandetron accelerator mass spectrometer at Dating and Materials Research Center, Nagoya University.
