PROBLEM TO BE SOLVED: To provide a light brake disc capable of preventing the occurrence of warp deformation due to braking by clarifying yield strength of an Al brake disc for suppressing warp deformation. SOLUTION: This brake disc is constituted by an Al base composite material produced by dispersing ceramic particles having average particle diameter of 1 to 20μm of 5 to 30 volume % in Al alloy containing Fe of 0.5 to 5.0 %, Si of 0.2 to 3.0 %, Cu of 0.5 to 3.0 %, Mg of 0.5 to 2.0 %, and Cr of 0.5 to 3.0 %.
