Abstract:
1. An electric shaver comprising: a main body to be gripped by a user; an outer blade provided to an end portion of the main body, the outer blade comprising longitudinal bars extending in a longitudinal direction of the outer blade and lateral bars extending in a lateral direction intersecting with the longitudinal direction, wherein the longitudinal bars and the lateral bars intersect to define blade holes; 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 let in the blade holes in cooperation with the outer blade, wherein the longitudinal bars are located in first and second portions of the outer blade and have hair raising portions configured to come in contact with hair upon movement of the outer blade on a skin surface to raise hair up from the skin surface, the outer blade has a curved shape in a side view, the first portion is a top portion of the curved shape, the second portion is an outer portion situated at either outer side, in the lateral direction, of the top portion of the curved shape, a contact pressure on the skin surface to be exerted by the outer blade in the first portion is greater than a contact pressure in the second portion, a cross-section of the longitudinal bars in the first portion have a different shape than a cross-section of at least one of the longitudinal bars in the second portion, hair raising performance in raising hair up from the skin surface by the longitudinal bars in the first portion is smaller than hair raising performance by the longitudinal bars in the second portion, the hair raising portions are formed into a tapered shape at an end, in the lateral direction, of the longitudinal bars, and a curvature radius of the end, in the lateral direction, of the longitudinal bars in the first portion is larger than a curvature radius of the end, in the lateral direction, of the longitudinal bars in the second portion.
