A brake pad 10 can brake a rotation of a disc 200. The brake pad 10 includes a friction material 12 provided on the side of the disc 200 and a back plate 11 bonded to the friction material 12 on the opposite side of the disc 200. A thickness of a central region of the back plate 11 in a rotational direction of the disc 200 is larger than thicknesses of both end regions of the back plate 11 in the rotational direction of the disc. In the case where a minimum value of the thicknesses of the end regions of the back plate 11 is defined as "h 1 [mm]" and a maximum value of the thickness of the central region of the back plate 11 is defined as "h 2 [mm]", h 1 and h 2 preferably satisfy a relationship of "h 2 -h 1
