Abstract
Official abstract text for this publication.
An electric shaver includes: a main body; an outer blade provided to an end of the main body and having a blade hole defined by a bar; and an inner blade provided inward of the outer blade and configured to reciprocate in a longitudinal direction of the outer blade to cut hair in the blade hole with the outer blade. The bar has a hair raising portion coming in contact with hair upon movement of the outer blade on a skin surface to raise hair up from the skin surface. A contact pressure on the skin surface to be exerted by the outer blade in a first portion of the outer blade is greater than that in a second portion of the outer blade. Hair raising performance in raising hair up from the skin surface in the first portion is smaller than hair raising performance in the second portion.
