Provided is a radiant heater device (1), comprising an electrode (4) that is embedded in a substrate section (2) and a plurality of heat generation units (5). The electrode (4) is formed using a material that has low resistivity. The area that is occupied by the electrode (4) is controlled. The heat generation units (5) are formed using a material that has high resistivity in order to generate heat and thereby produce radiant heat. The electrode (4) and the heat generation units (5) are electrically connected within the substrate section (2). The plurality of heat generation units (5) is arranged in parallel between a pair of electrodes (41, 42). The electrode (4) and the heat generation units (5) are formed to have a film-like shape, and the thermal capacity thereof is controlled. As a result, the temperatures of the heat generation units (5) rise quickly in response to electrification. In addition, the temperatures of the heat generation units (5) decrease quickly when an object comes into contact therewith.
