PROBLEM TO BE SOLVED: To provide a disc brake pad having a resin-made back plate achieved in the weight reduction and capable of using a magnetic force in a manufacturing process. SOLUTION: The disc brake pad consists of a resin-made back plate and an insulating member. The brake pad is characterized in that the back plate is made of a thermosetting resin that contains 1 to 50 weight percent of a siderofiber of which the diameter is not more than 200μm when the total weight of the back plate is assumed as 100 weight percent, or 1 to 50 weight percent of iron powder, or the iron powder and an iron oxide of which the average particle diameters are not more than 500μm, and that the back plate carries a magnetic responsivity.
