Abstract
A rotary electric shaver includes an outer blade having hair inlets, and an inner blade rotating while coming into sliding contact with an inner surface of the outer blade. The inner blade includes a first small blade erected from a base surface, and a second small blade erected from the base surface. A first front end blade edge is formed in a front end part of an upper end part in a rotation direction. A second front end blade edge is formed in a front end part of an upper end part. An angle of a rake angle of the first front end blade edge is relatively small and an angle of a rake angle of the second front end blade edge is relatively large.

A rotary electric shaver comprising:
- a blade unit including an outer blade in which a plurality of hair inlets are formed, and an inner blade rotating while coming into sliding contact with an inner surface of the outer blade, wherein
- the inner blade includes a plurality of first small blades erected from a base surface, and a plurality of second small blades erected from the base surface in a direction opposite to a rotation direction,
- in the first small blades, a first front end blade edge configured to cut hairs entering the hair inlets is formed in a front end part of an upper end part in the rotation direction,
- in the second small blades, a second front end blade edge configured to cut the hairs entering the hair inlets is formed in a front end part of an upper end part in the rotation direction, and
- an angle of a rake angle of the first front end blade edge is formed to be a relatively small angle and an angle of a rake angle of the second front end blade edge is formed to be a relatively large angle.
