## Abstract

The present invention relates to heat-resistant paint which is capable of forming paint film that inhibits whitening even in high-temperature environments on the order of 350-650° C. The heat-resistant paint of the present invention contains silicone resin and/or epoxy resin as well as black pigment, wherein, said black pigment contains manganese and copper, the content of manganese in said black pigment is 25-45 mass % by MnO conversion, the content of copper in said black pigment is 5-25 mass % by CuO conversion, and the content of silicon in said black pigment is 3 mass % or less by SiO2 conversion.
