A bicycle disc brake pad is used in a disc brake device and is configured to reduce restrictions on backplate material in a disc brake pad for a bicycle in which a friction member is bonded to a backplate by a diffusion bonding method. The bicycle disc brake pad has a backplate, a spray coating layer and a friction member. The surface of the backplate has a spray coat surface. The spray coating layer is a copper or copper alloy layer formed on the spray coat surface. The friction member is bonded to the spray coating layer by a diffusion bonding method. Preferably, the spray coat surface of the backplate is formed with a rough surface on at least part of the spray coat surface.
