Within recent years, the meteorite has become an interesting material on the geochemistry and the cosmochemistry. The Komagome iron meteorite had been one of the doubtfull meteorite in Japan. According to literatures, it fell 18th April 1926 in Tokyo and was 238g (weight). The present paper describes the following results. Ni and Co contents of this iron meteorite were about 8.0% and about 0.5% respectively. On the distribution pattern of the schreibersite, it was shown by the electron probe X-ray microanalyzer. The schreibersite was always occupied the center of the troilite phase.
