Abstract
The heater device is provided with a heater main body, and radiates radiant heat from the heater main body toward an object. The heater main body includes a sheet-like heat generating layer that generates heat and radiates the radiant heat, and a sheet-like heat insulating layer that is disposed on the side opposite to the object of the heat generating layer. The heat insulating layer has a sheet-like first layer having voids and a sheet-like second layer having voids arranged side by side in a thickness direction of the heat insulating layer with respect to the first layer. A porosity of the second layer is higher than that of the first layer.
