摘要
PROBLEM TO BE SOLVED: To provide an infrared ray source having a larger total amount (integration amount) of infrared ray of a wavelength region in some range including a predetermined wavelength.;SOLUTION: A infrared ray source 101 includes a heating element 15, and a radiator 23 having an outermost surface composed of a metal, and radiates infrared ray having a peak at a predetermined wavelength. On the surface of the radiator 23, micro cavities MC having a micro rectangular concave cross section are arranged two-dimensionally at a constant period. Following relations are satisfied; 0.6W/P0.9, 0.4D/W0.8, where P is the constant period, W is the width of the micro cavity MC, and D is the depth of the micro cavity MC.;COPYRIGHT: (C)2014,JPO&INPIT
