PROBLEM TO BE SOLVED: To provide a disc brake device which can suppress noise in braking, and to provide a pair of brake pads.SOLUTION: A disc brake device 1 comprises: a disc rotor 2 which can rotate around a rotation axis line; a pair of brake pads 3, 4 which are opposing each other and are arranged on both sides of the disc rotor 2 with respect to an axial direction along the rotation axis line; and a pressing mechanism 6 which can press the pair of the brake pads 3, 4 against the disc rotor 2 from both sides of the disc rotor 2 by pistons 9 which are opposing each other and are arranged on both sides of the disc rotor 2 with respect to the axial direction. The pair of the brake pads 3, 4 have friction materials 7 which oppose to friction faces 2a of the disc rotor 2, respectively, and have slits 10 formed in the friction materials 7. Numbers of the slits 10 not passing through pressed regions which are pressed by the pistons 9 differ from each other. |
