PROBLEM TO BE SOLVED: To provide a radiation heater device capable of suppressing a temperature of a portion in contact with an object.SOLUTION: A radiation heater device 1 comprises: an electrode 4 buried in a substrate portion 2; and a heating portion 5. The heating portion 5 includes a plurality of heating wires 50. The heating wires 50 are connected in parallel so as to form a plurality of parallel groups 51, 52, and 53 by electrodes 55 and 56. Furthermore, the parallel groups 51, 52, and 53 are connected in series by the electrodes 55 and 56. The heating portion 5 is set to be able to reach a radiation temperature at which radiant heat that can make a person feel warm can be radiated. A thermal resistance of the heating portion 5 is set such that a temperature of a portion in contact with an object falls to a suppression temperature lower than the radiation temperature when the object contacts the portion on a surface. The electrode 4 and the heating portion 5 are formed into a film shape to suppress thermal capacities thereof. A temperature of the heating portion 5 quickly rises in response to current-carrying. The temperature of the heating portion 5 quickly falls when an object contacts a portion.SELECTED DRAWING: Figure 2 |
