PROBLEM TO BE SOLVED: To provide a far infrared radiation panel heater unit holding a high thermal radiation efficiency. SOLUTION: In the far infrared radiation panel heater unit 22, a structure obtained by laminating a far infrared radiation plate 6, a face heat generating member 7 and a pressing plate 19 is attached to a heater attaching panel 5. In addition thereto, a heat insulating material 8 is disposed between the face heat generating member 7 and the pressing plate 19 composed of an aluminum deposited steel plate, and the pressing plate 19 is not a flat plate and has a main surface to which an annular (preferably, ring) bead work 12 and linear bead works 13 in the vertical and horizontal directions are applied. The pressing plate 19 is bent in the same direction as that of the far infrared radiation plate 6 by heating so that the face heat generating member 7 is bent in the same manner to hold the adhesion between both the members and obtain the high thermal radiation efficiency.
