<p>An infrared radiation device (20) is provided with an infrared heater unit (30) having a filament (32) radiating an electromagnetic wave containing infrared when heated, a lower wall part (61) reflecting upward an infrared beam radiated directly below from the filament (32) when a predetermined direction is downward, and a reflective body (62) having a reflective surface (63) reflecting an infrared beam radiated upward from the filament (32) so as to reach lower than the lower wall part (61). An insulation container (60) is provided with a second flow path (67) allowing a second refrigerant to flow through. The infrared radiation device (20) is provided with side wall parts (64a to 64d) for blocking an infrared beam radiated from the filament (32) in a front, back, left or right direction, orthogonal to the downward direction. The infrared radiation device (20) is provided with the insulation container (60) covering the filament (32), and the insulation container (60) has a hole (65) serving as an exit from the insulation container (60) for an infrared beam.</p> |
