Abstract:
1. An infrared sensor comprising: an electrical insulating film sheet; first and second temperature sensor devices which are provided on one side of the electrical insulating film sheet, and are located at a distance from each other; first foil conductor patterns which are formed on the one side of the electrical insulating film sheet, and are connected to the first temperature sensor device; second foil conductor patterns which are formed on the one side of the electrical insulating film sheet, and are connected to the second temperature sensor device; and an infrared reflector film which is provided on another side of the electrical insulating film sheet, and is opposite only the second temperature sensor device across the electrical insulating film sheet, wherein a portion of the first foil conductor patterns is arranged around the first temperature sensor device and has a width greater than the rest of the first conductor patterns so that the first foil conductor patterns occupy a larger surface area than a surface area occupied by the second foil conductor patterns.
