Infrared sensor and a circuit board equipped therewith

Abstract

An infrared sensor allows for a large temperature difference between a temperature sensor for the detection of infrared rays and a temperature sensor for temperature compensation; a reduction in size; and a low manufacturing cost. The infrared sensor comprises: an electrical insulating film sheet; first temperature sensor and second temperature sensor 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 formed on one side face of the electrical insulating film sheet, and are connected to the first temperature sensor; second foil conductor patterns formed on the one side of the electrical insulating film sheet, and are connected to the second temperature sensor; and an infrared reflector film provided on the other side of the electrical insulating film sheet, and is opposite the second temperature sensor across the electrical insulating film sheet.
