<P>PROBLEM TO BE SOLVED: To provide a coating or a coating film excellent in heat insulation property or heat shielding property. Ž<P>SOLUTION: The heat insulation coating or heat insulation coating film includes compounds with chemical composition formulas of CaH2O2 and Na<SB>3</SB>O<SB>4</SB>P as heat insulation components, wherein the heat insulating components of 3-30 wt.% are contained with respect to the total added components. Also the compound with the chemical composition formula Na<SB>3</SB>O<SB>4</SB>P of ≥0.7 wt.%, desirably ≤2 wt.% with respect to the total added components, and furthermore Fe<SB>2</SB>O<SB>3</SB>and/or MgO are contained therein as additives, wherein Fe<SB>2</SB>O<SB>3</SB>of ≤0.02 wt.% and MgO of ≤0.6 wt.% are contained with respect to the total added components.
