<P>PROBLEM TO BE SOLVED: To provide a light detector, a light detecting apparatus, an infrared detector and an infrared detecting apparatus that have high detection sensitivity. <P>SOLUTION: The infrared detector 10 which converts entering infrared IR into light in a different wavelength band, and which detects the converted light in the different wavelength band includes: a convex-concave structure 28 provided on a light acceptance surface of the infrared detector 10, and a metal film 24 covers an outer circumferential face of the light detector 10 other than the light acceptance surface thereof. Light which enters the infrared detector after passing through the convex-concave structure 28 and the converted light in the different wavelength band are confined inside a cell 11: by causing the entering light to be reflected on the metal film 24; by causing light reflected on the metal film 24 to be reflected on the convex-concave structure 28; and by causing the converted light in the different wavelength band to be reflected between the metal film 24 and the convex-concave structure 28. <P>COPYRIGHT: (C)2011,JPO&INPIT |
