To provide an infrared sensor that allows heat to be efficiently transferred from an insulating film to a heat sensitive element and has a good responsivity. The infrared sensor according to the present invention includes an insulating film; a pair of first adhesive electrodesA that is patterned on either surface of the insulating film; a pair of first terminal electrodesA that is patterned on either surface of the insulating film; a first heat sensitive elementA that is provided on either surface of the insulating film and is connected to the pair of first adhesive electrodes; a pair of first pattern wiring partsA that is patterned on either surface of the insulating film with one end thereof being connected to the pair of first adhesive electrodes and the other end thereof being connected to the pair of first terminal electrodes; and a heat transfer film

Infrared sensor

The infrared sensor according to the present invention includes an insulating film; a pair of first terminal electrodes; a pair of second terminal electrodes; a first heat sensitive element; a second heat sensitive element; a pair of first pattern wiring parts and a pair of second pattern wiring parts that are patterned on either surface of the insulating film; an infrared-receiving region that is provided on the other surface of the insulating film so as to oppose to the first heat sensitive element; and an infrared reflection film that is formed on the other surface of the insulating film so as to avoid the infrared-receiving region and to cover at least the portion immediately above the second heat sensitive element, wherein the infrared reflection film has a thermal coupling part in proximity to a portion of the first pattern wiring part.
