PROBLEM TO BE SOLVED: To provide a far-infrared ray panel heater with high heat radiation efficiency. SOLUTION: The far-infrared ray panel heater device is composed of a heating panel unit formed by laminating at least a far-infrared ray radiation plate, a flat heat radiation body, and a holder part, and a wiring pattern of a resistant wire 15, arranged on the heat radiation body as a heat source, is patterned or heat controlled so that the central area C of the flat heat radiation body 17 becomes high temperature ahead of peripheral area, and the whole part of the far-infrared ray radiation plate closely contact with the flat heat radiation body without gap by convexly warping to the heat radiation body side to maintain a high heat radiation efficiency.
