A radiant heater device for generating a radiant heat, includes a substrate portion having a plate shape and made of an electrically insulating material, a surface member having a sheet shape and disposed on one surface side of the substrate portion, and a heat generation portion formed on the other surface side of the substrate portion. The surface member is formed of a fiber fabric that is provided with a space portion recessed toward the substrate portion in a thickness direction of the surface member and that restricts a heat transfer in a surface direction of the surface member by the space portion.
