Abstract: A blade of a hair removal device according to the present disclosure includes a fixed blade having a fixed blade bar and a fixed blade groove, and a movable blade having a movable blade bar and a movable blade groove. The movable blade bar is formed such that a bar width in a reciprocating sliding direction is larger than a groove width of the fixed blade groove in the reciprocating sliding direction. In the fixed blade bar, a bar width in the reciprocating sliding direction is larger than a groove width of the movable blade groove in the reciprocating sliding direction. In the fixed blade groove and the movable blade groove, a blade groove angle at least on an opening side is a positive angle with an intersection positioned on a depth side. This configuration provides a blade of a hair removal device capable of suppressing deformation.
