Abstract
A thermal insulation structure for a vehicle window device is provided with a heater is disposed on a vehicle interior side, a heat-receiving component that is provided between the window and the heater, and that, by receiving heat from the heater, imparts radiant heat to the window, and a thermal insulation layer that is provided at a surface of the heater on an opposite side from the heat-receiving component, wherein the thermal insulation layer is formed by mutually superimposing a plurality of thermal insulation materials, and of the plurality of thermal insulation materials, a thermal insulation material on a closest side to the heater has greater heat resistance than a thermal insulation material on a furthest side from the heater, and the thermal insulation material on the furthest side from the heater has a lower thermal conductivity than the thermal insulation material on the closest side to the heater.
