PURPOSE: A ceramic product for an electric heating mat obtained by coating a thermochromic pigment on ceramic is provided. The ceramic product permits a user to know the temperature transmitted to ceramic, therefore an unnecessary consumption of the electric heating mat can be avoided. CONSTITUTION: A coating material(60) containing a thermochromic pigment which exhibits a visible change according to a change in temperature is coated on the surface of ceramic(20). It is attached on the upper surface of an electric heating mat(10) to emit far-infrared radiation by heating.
