PROBLEM TO BE SOLVED: To provide an electric razor blade excellent in corrosion resistance, an electric razor comprising such an electric razor blade, as well as a metal powder for powder metallurgy which enables the easy manufacture of an electric razor blade of high corrosion resistance and a manufacturing method of the electric razor blade.;SOLUTION: An electric shaver (electric razor) comprises an outer blade 121 and an inner blade 123. The outer blade 121 and the inner blade 123 (electric razor blade) are materials consisting mainly of Co, and Cr in a proportion of 16 mass% or more and 35 mass% or less, Mo in a proportion of 3 mass% or more and 12 mass% or less, Si in a proportion of 0.3 mass% or more and 2.0 mass% or less, and N in a proportion of 0.09 mass% or more and 0.5 mass% or less, and are configured of a sinter of a metal powder. Further, a part of Si are contained a silicon oxide, and the ratio of Si contained as silicon oxide among Si is preferably 20 mass% or more and 80 mass% or less.;COPYRIGHT: (C)2016,JPO&INPIT
