PURPOSE: A black coating composition is provided to provide a black coating film which has a high resistance, heat resistance, chemical resistance and high film hardness and has durability even in high temperature process. CONSTITUTION: A black coating composition comprises: a black material, highly durable insulating metal oxide particle, a polymerizable compound and a polymerization initiator. The highly durable insulating metal oxide particle has an average particle diameter of 50 nm and a polydispersity of 2.0 or less. The highly durable insulating metal oxide is surfaced treated by a silane coupling agent. The black material comprises one or more inorganic pigment selected from carbon black, titan black, metal oxide, composite oxide, metal sulfide, and metal carbonate.
