The interior blade includes a horizontal surface (4), a vertical surface (5), and a relief surface (6) provided between the horizontal surface (4) and the vertical surface (5), and is elastically pushed upward by the interior blade pushing-up means (15a). The blade further includes a sheet-shaped exterior blade (2) having a plurality of blade apertures (1). A bottom surface of the exterior blade is elastically contacted with the horizontal surface (4) of the interior blade (3) by a pushing force of the interior blade pushing-up means (15a). Upon driving the drive element (15), the interior blade (3) is moved laterally such that the horizontal surface (4) of the interior blade (3) rubs against the bottom surface of the exterior blade (2), and hair introduced into the blade aperture (1) of the exterior blade (2) is held between the horizontal surface (4) of the interior blade (3) and the exterior blade (2) in accordance with a lateral movement of the interior blade (3) and cut by an edge (2a) of the exterior blade (2).
