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.
