An embodiment discloses a vehicle disc brake including a caliper body, a banjo and a banjo bolt. An acting portion of the caliper body has a cylinder bore accommodating a piston. The caliper body is formed through a gravity casting method. A gate mark is formed on the bottom wall of the cylinder bore as a result of cutting the gate after the caliper body has been cast, and the gate mark includes a worked surface and a projecting surface. A union hole communicating with a hydraulic pressure chamber and a locking hole receiving the locking projection of a banjo are opened in the worked surface. And, an uneven portion is provided between the worked surface and the projecting surface.
