An internal ventilation type disk brake is provided to improve the heat emission performance by forming a heat induction element that allows a great amount of air to flow between an outer wall of a cooling air channel and an outer surface of the heat induction element. An internal ventilation type disk brake(1) comprises two friction rings(2,3) that are spaced apart from each other by a rib(4). A cooling air channel(5) is formed between the friction rings. At least one heat induction element(6) is disposed between the friction rings. The two friction rings and the heat induction elements form a single piece molding body(7). A part of heat induction elements is molded into the single piece molding body. A part of the heat induction elements protrude into the cooling air channel of the brake disk. The heat induction element is disposed on a division surface(8) which extends parallel to the friction ring.
