PURPOSE:To solve problems of a decrease in thermal impact resistance due to a difference of thermal expansion coefficients, deterioration of thermal conductivity of a flame-sprayed film of disadvantages of prior art in a metal substrate with an insulating layer. CONSTITUTION:In order to form an insulating layer by flame spraying ceramics on a surface of a metal substrate, the ceramics are flame-sprayed on the surface of the substrate, the sprayed ceramic layer is irradiated with a laser to impregnate an insulator.
