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: An outer blade for a hair cutting device, the outer blade being mounted to an end of a main body of the hair cutting device, includes bars that each have a shape of a rectangular stick and are arranged at predetermined intervals. The outer blade also includes, at a skin-surface-contact-side first face of each of the bars, an agent holding part configured to hold an agent that is a substance having a predetermined effect on a skin surface, the agent holding part being a surrounded recess heading from the skin-surface-contact-side first face of the bar toward an inner-blade-side second face of the bar. Thus, the agent such as foam or gel can be held by the agent holding part at the skin-surface-side face of the outer blade, and friction can be reduced between the outer blade and the skin surface by the agent held by the agent holding part.
