Abstract: An outer blade of an electric shaver has slits. Each of the slits includes: a first slit portion; a second slit portion positioned in a displaced manner from the first slit portion in a length direction of the outer blade; and a connecting slit portion connecting the first slit portion to the second slit portion. A displacement width in the length direction of the outer blade between the first slit portion and the second slit portion is set equal to or larger than at least one of widths of connecting portions of the first slit portion and the second slit portion connected to the connecting slit portion.

Abstract: This electric shaver has outer blades, inner blades, an inner-blade joint component, and skin-entry prevention parts. The outer blades have outer-blade holes. The inner blades have main inner-blade walls, multiple blade pieces, inner-blade holes, and internal inner-blade spaces. The inner blades move back and forth relative to the outer blades so as to cut hair that has entered through the outer-blade holes. The main inner-blade walls are connected to the inner-blade joint component. The internal inner-blade spaces are bounded by the main inner-blade walls and the multiple blade pieces. The skin-entry prevention parts are located inside the internal inner-blade spaces, at positions that correspond to the inner-blade holes, and are structured so as to contact skin that has entered the internal inner-blade spaces via the inter-blade holes.
