A support arm 27 that is rockably supported on one end of a grip portion 2 and projects from the one end is provided. Both ends of a blade head 3 are supported by the support arm 27 such that the blade head 3 can rock around an axis extending along a reciprocating direction of an inner blade 14, and an axial direction of the rocking motion of the support arm 27 with respect to the grip portion 2 is set in a direction intersecting with the reciprocating direction of the inner blade 14. This configuration achieves an electric shaver capable of increasing the movable range of the blade head while preventing a main body from increasing in size.
