A disk brake pad controls rotation of a disk rotor by pushing a friction surface against the disk rotor while it is rotating. The disk brake pad is formed with respective chamfered portions at respective end portions of the disk brake pad at the incoming and outgoing disk-rotor-rotation sides thereof. An edge of an end portion of the friction surface of the disk brake pad at the incoming disk-rotor-rotation side, and an edge of an end portion at the outgoing disk-rotor-rotation side are formed in a stepped bending shape such that a length of the friction surface in a circumferential direction of the disk rotor becomes shorter in a center of rotation direction of the disk rotor.
