A disc brake is provided to integrally form an inner pad plate with a piston and integrally form an outer pad plate with a caliper housing to prevent rattle noise from occurring. A caliper housing(10) includes a first caliper housing(11) and a second caliper housing(12). The first caliper housing is provided with a cylinder(11a) allowing a piston(20) to move back and forth. The second caliper housing is formed at one side thereof with a finger part(12a). The first caliper housing is coupled to the second caliper housing by using a bolt. The cylinder is provided at the rear portion of the caliper housing. The cylinder is provided the inside thereof with a seal(11b) made of an elastic material to recover the piston. The finger part of the second caliper housing is bent from a front part of the caliper housing downward to surround the outer pad plate.
