PROBLEM TO BE SOLVED: To provide a disc brake capable of restraining its weight from increasing by minimizing the width of the disc rotational direction of an intermediate joint part, thus preventing the size of the whole caliper in the disc rotational direction from increasing. SOLUTION: A plurality of caliper division bodies 23A, 23B for slidably restraining pistons 22a, 22b are provided. The caliper division bodies 23A, 23B have an opposing piston type caliper 15 for jointing the joint parts 25a, 25b, 25c at both ends and an intermediate portion in the disc rotational direction with each other by tie bolts 27a, 27b, 27c along a disc axial direction. A fluid pressure introduction hole 47 for introducing fluid pressure between a bore and a piston is formed in line with the disc axial direction to a joint bolt hole 26c in which the tie bolt 27c of the intermediate joint part 25c is provided.
