PROBLEM TO BE SOLVED: To obtain a far infrared radiating coating material from which a ceramic powder will not fall off even when blended in high percentage in the coating material and which has good adherence and adhesiveness to a base material by blending ceramics having a mean particle diameter below a specified value, a hydroxylated resin, and a polyisocyanate compound. SOLUTION: The material contains coating components comprising ceramics (A) having a mean particle diameter of at most 100μm, a hydroxylated resin (B), and at least one compound (C) selected from a polyisocyanate compound having at least two isocyanato groups in the molecule and a urethane prepolymer, wherein the total of components B and C is 25-550 pts.wt. based on 100 pts.wt. component A, and the weight ratio of component B to component C is (15:85) to (90:10). Examples of component A include SiO2 , Al2 O3 and TiO2 . Examples of component B include a hydroxylated polyester resin and an acrylic resin. A pigment can be optionally blended with this coating material.
