To provide a brake pad which contributes to reduction in size/weight as an overall disc brake apparatus and is capable of suppressing rattle noise or squeal noise in comparison with a conventional brake pad for the disc brake apparatus.
An outer side brake pad 80 for a floating type disc brake apparatus 10 is held by a caliper 30 and transmits braking torque to a support 12. The caliper 30 includes a plurality of through holes 48a, 48b having a circumferential direction length of a rotor 100 equal to a radial direction length of the rotor 100 on inner walls of claw portions 44a, 44b. There are provided a plurality of protruding portions 88a, 88b which are loosely fitted to the through holes 48a, 48b, respectively. Each of the protruding portions 88a, 88b has a long axis and a short axis in its front projection shape and is characterized in that the long axis is along the radial direction of the rotor 100, the short axis is along the circumferential direction of the rotor 100, and an abutting part with the support 12 is provided at an outer circumferential side in the radial direction of the rotor 100 rather than an outer edge of the rotor 100.
