Blade of a hair clipper includes a fixed blade, and a movable blade for cutting hair by reciprocating and sliding on fixed blade in one direction. Furthermore, the fixed blade also includes sliding contact surface P2 on which the movable blade can slide, and skin contact surface P3 that can come into contact with skin. In a first state, sliding contact surface P2 is inclined with respect to skin contact surface P3 such that a distance between sliding contact surface P2 and skin contact surface P3 is decreased toward a distal end side of the fixed blade, and movable blade is configured to be slidable on sliding contact surface P2 of fixed blade in an intersecting direction intersecting with the one direction. Distal end part of fixed blade includes uniform part having a uniform thickness in a thickness direction intersecting the one direction and the intersecting direction.
