The identification of Fe II lines in the spectrum of SN 1972e in NGC 5253 reported by Kirshner and Oke (1975) provides strong observational evidence for Fe production in type I supernovae. It is found that the observed amount of Fe in type I supernovae may be sufficient to give the Fe abundance in the solar neighborhood. The implications of Fe production in type I supernovae for the chemical history of the Galaxy are discussed. It is suggested that the Fe nuclei in cosmic rays are accelerated in type I supernovae.
