PROBLEM TO BE SOLVED: To provide an electric razor which makes suitable the arrangement of a cutting edge for rough shaving and a cutting edge for finish shaving and the projection relation of each of the cutting edges, can effectively perform the cutting of a frizzy mustache and the finish shaving, and can repeatedly and exactly cut the frizzy mustache especially in a jaw part. SOLUTION: A first cutting edge 11 for rough shaving, a second cutting edge 12 for finish shaving, and a third cutting edge 13 for rough shaving are formed in a razor head 6. The upper end of the second cutting edge 12 is made to project upwards from the upper end of the first cutting edge 11 and the upper end of the third cutting edge 13 is made to project upwards from the upper end of the second cutting edge 12. The upper end of the third cutting edge 13 is located below a tangent L which connects the outer peripheral face of the first cutting edge 11 and the outer peripheral face of the second cutting edge 12 and the upper end of the third cutting edge 13 is made to project beyond the upper end of the second cutting edge 12. The projection size difference H1 of the second cutting edge 12 and the first cutting edge 11 is set larger than the projection size difference H2 of the third cutting edge 13 and the second cutting edge 12.
