Abstract
A heat-insulating layer exhibiting high resistance to cracks, peeling, deformation, and gasoline and high heat insulation is obtained on the wall surface of an engine member (). First, a heat insulator layer including a silicone-based resin and hollow particles containing a Si-based oxide is formed on a wall surface of the engine member (). Then, Si-based oxide is produced through oxidation of a silicone-based resin in at least part of the surface of the heat insulator layer by heating the surface of the heat insulator layer. Thereafter, a catalytic metal is added to the silicone-based resin in the surface of the heat insulator layer and/or Si-based oxide derived from the hollow particles. Using the catalytic metal as nuclei, electroless plating is performed. In this manner, a heat-insulating layer () in which the surface of the heat-insulating film () is covered with a plating film () is obtained.
