PROBLEM TO BE SOLVED: To provide an infrared sensor that is inexpensive and can be corrected for variation of detection sensitivity, and a method for adjusting sensitivity of an infrared sensor.SOLUTION: The infrared sensor includes: an insulating film 2; a first heat sensitive element and a second heat sensitive element separated from each other and disposed on one surface of the insulating film; a conductive first wiring film connected to the first heat sensitive element and a conductive second wiring film connected to the second heat sensitive element, both formed on the one surface of the insulating film; and an infrared reflection film 6 formed on the other surface of the insulating film and opposing to at least the second heat sensitive element. The infrared reflection film includes a plurality of unit reflection film portions 6a patterned as divided in a region on the other surface of the insulating film, the region opposing to the first heat sensitive element.SELECTED DRAWING: Figure 1 |
