A disc brake includes brake pads (7), which are slidably received on either side of a brake disc within guide portions (6) of the disc brake, and including a spring arrangement (10) for spring cushioning the brake pads (7). Disc brakes of this type are frequently used in motor vehicles. To improve the spring cushioning of the brake pads, the spring arrangement (10) is equipped with at least one radial spring element (11) for radially clamping the brake pads (7) with respect to the guide portions (6), at least one axial spring element (22) for axially clamping the brake pads (7) in relation to each other, and at least one tangential spring element (18) for tangentially clamping the brake pads (7) in relation to the guide portions (6). The three spring elements (11, 18, 22) act in different spatial dimensions and can be embodied as separate components which are independent of each other.
