<p><P>PROBLEM TO BE SOLVED: To provide an infrared sensor which achieves a large difference in temperature between a heat sensitive element for infrared detection and a heat sensitive element for temperature compensation, and which has a structure that can be downsized and realized at low cost. <P>SOLUTION: An infrared sensor includes: an insulation film 2; a first heat sensitive element 3A and a second heat sensitive element 3B which are provided to be away from each other on one surface of the insulation film 2; multiple pairs of conductive wiring films 4 which are formed on such one surface of the insulation film 2, and which are connected to the first heat sensitive element 3A and the second heat sensitive element 3B separately; a light receiving area 5A which is provided on another surface of the insulation film 2 so as to face the first heat sensitive element 3A; and an infrared reflecting film 6 which is provided on such another surface of the insulation film 2 so as to face the second heat sensitive element 3B. The infrared reflecting film 6 is formed so as to cover a periphery of the light receiving area 5A. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
