Abstract: The present invention is a vehicle disc brake for which incorrect installation of a friction pad can be prevented with a simple structure. The disc brake is provided with incorrect installation-preventing parts with which, if a friction pad (4) is installed with an incorrect installation orientation when a pair of tabs (10, 11) provided on the disc entry-side and disc exit-side of the back plate (4d) of a friction pad (4) is installed into pad guide grooves (9) formed on a caliper body (3), the tabs bump into the caliper body (3) and prevent the incorrect installation. The incorrect installation-preventing parts are formed from caliper-side recesses (9d, 9e), which are formed in the pad guide grooves (9) towards the center of the caliper body, and tab-side protrusions (10a, 11a), which have shapes that correspond to the caliper-side recesses (9d, 9e).
