A disc brake pad that is used in a disc brake device to be disposed in a vehicle and that is adapted to be pressed against a disc disposed so as to rotate along with one of an axle and a wheel in the vehicle, the disc brake pad comprising: a lining member (21; 40; 41; 42; 43; 44) that is adapted to be pressed against a frictional braking face of the disc; and a lining support portion that is adapted to support the lining member (21; 40; 41; 42; 43; 44) and is adapted to be held so as to be able to swing relative to a caliper body that is adapted to be driven by a brake cylinder device of the disc brake device, wherein the lining support portion is provided with a base portion that is adapted to support the lining member (21; 40; 41; 42; 43; 44), and a load transfer portion (24a, 24b) that is provided to be integrated with or fixed to the base portion and is adapted to transfer a load from the caliper body to the base portion, and the load transfer portion (24a, 24b) is provided at a position on the base portion at which a load that generates surface pressure, which is surface pressure generated between the lining member (21; 40; 41; 42; 43; 44) and the frictional braking face when the lining member (21; 40; 41; 42; 43; 44) is pressed against the frictional braking face, is adapted to act on the base portion in a manner such that a magnitude of the surface pressure is inversely proportional to a magnitude of a distance from a position of a rotational centerline of the disc in a radial direction of the disc, characterized in that the disk brake pad is configured such that the load acting from the disk brake pad on a ring-like element of the disk, whose dimension in the radial direction of the disk is a unit dimension, is constant regardless of the position of the ring-like element in the radial direction of the disk from the rotation centerline of the disk, and wherein the area of a lining member-side element of the lining member, whose dimension in the radial direction of the disk is a unit dimension, is proportional to the radial dimension (r) of the lining member-side element from the rotation centerline of the disk. a lining member (21; 40; 41; 42; 43; 44) that is adapted to be pressed against a frictional braking face of the disc; and a lining support portion that is adapted to support the lining member (21; 40; 41; 42; 43; 44) and is adapted to be held so as to be able to swing relative to a caliper body that is adapted to be driven by a brake cylinder device of the disc brake device, wherein the lining support portion is provided with a base portion that is adapted to support the lining member (21; 40; 41; 42; 43; 44), and a load transfer portion (24a, 24b) that is provided to be integrated with or fixed to the base portion and is adapted to transfer a load from the caliper body to the base portion, and the load transfer portion (24a, 24b) is provided at a position on the base portion at which a load that generates surface pressure, which is surface pressure generated between the lining member (21; 40; 41; 42; 43; 44) and the frictional braking face when the lining member (21; 40; 41; 42; 43; 44) is pressed against the frictional braking face, is adapted to act on the base portion in a manner such that a magnitude of the surface pressure is inversely proportional to a magnitude of a distance from a position of a rotational centerline of the disc in a radial direction of the disc, characterized in that the disk brake pad is configured such that the load acting from the disk brake pad on a ring-like element of the disk, whose dimension in the radial direction of the disk is a unit dimension, is constant regardless of the position of the ring-like element in the radial direction of the disk from the rotation centerline of the disk, and wherein the area of a lining member-side element of the lining member, whose dimension in the radial direction of the disk is a unit dimension, is proportional to the radial dimension (r) of the lining member-side element from the rotation centerline of the disk.
