The invention relates to a heat-insulating member for a vehicle, a heat-insulating film, and a method for manufacturing the heat-insulating member for the vehicle. Provided are: a heat-insulating film which is formed on the top surface of a piston and which does not cause peeling even when used in harsh environments such as the interior of a combustion chamber of an engine; and a heat-insulating member for a vehicle, said heat-insulating film being formed on the top surface of the piston. This heat-insulating member for a vehicle imparts heat-insulating properties by forming a heat-insulating film (1) on at least a part of the surface of a heat-insulating member (2) such as a piston of an engine, said heat-insulating film (1) comprising at least an inorganic compound layer (10). The inorganic compound layer (10) is formed by dispersing one or more kinds of scaly inorganic particles (12) selected from mica, talc and wollastonite in an inorganic compound (11) formed by alkoxide, and has a Vickers hardness (HV)
