RADIANT HEATER DEVICE

PROBLEM TO BE SOLVED: To inhibit the temperature rise of a portion contacting with an object.SOLUTION: A radiant heater device 1 comprises: multiple heat radiation parts 3; and multiple heating parts 4. The heat radiation parts 3 are formed into thin plates. The multiple heat radiation parts 3 are placed being dispersed. A low heat conduction part 6 is provided between the adjacent two heat radiation parts 3. Each lower heat conduction part 6 is provided mainly by a resin material forming a substrate part 2. Each low heat conduction part 6 encloses an entire periphery of the heat radiation part 3, thereby thermally separating the multiple heat radiation parts 3 from each other. The heat radiation parts 3 radiate radiation heat by heat generated by the heat generation parts 4. When an object contacts with a surface of the device 1, heat of a specific heat radiation part 3 located immediately below the object is radiated to the object. Further, the low heat conduction part 6 inhibits heat from being transmitted from a periphery of the specific heat radiation part 3 to the specific heat radiation part 3. Thus, the temperature rise is inhibited in a portion of the radiant heater device which contacts with the object.
