<p><P>PROBLEM TO BE SOLVED: To provide an infrared sensor that can restrain effects of radiant heat from a housing. <P>SOLUTION: An infrared sensor includes: an insulation film 2; a first heat sensitive element 3A and a second heat sensitive element 3B provided apart from each other on a surface of the insulation film 2; a first conductive wiring film 4A connected to the first heat sensitive element 3A and a second conductive wiring film 4B connected to the second heat sensitive element 3B, which are formed on the surface of the insulation film 2; an infrared reflection film 6 provided on the other surface of the insulation film 2 opposing to the second heat sensitive element 3B; and a housing fixed to the other surface of the insulation film to support the insulation film and including a storage part for storing therein the first heat sensitive element and the second heat sensitive element. The first wiring film 4A is arranged and formed around the first heat sensitive element 3A to have an area greater than that of the second wiring film 4B. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
