Abstract: Protruding portions protruding in a direction of approaching a disc rotor are integrally formed in a locking plate portion of a pad spring. Moreover, an insulating resin coating is formed on a front surface side (surface in a region opposed to an outer peripheral surface of the disc rotor) of the locking plate portion. The coating film formed on the front surface of the locking plate portion flows downward by its own weight before the coating material is solidified. As a result, the coating film formed on bottom surfaces (front surfaces of protrusions) of the protruding portions is thinner in film thickness than that of the coating film in other region.
