An internally ventilated disc brake has a number of main ribs which are arranged between two brake discs, delimit an air guide duct and are of blade-shaped design and run radially. Provided between the main ribs which extend over the length of the duct is at least one blade-shaped intermediate rib which runs approximately parallel to the adjacent main ribs and has a shorter length than these main ribs. In particular, the intermediate ribs and the main ribs are arranged symmetrically in relation to a central rubbing radius of the brake disc, the intermediate rib being in each case arranged centrally between two main ribs.
