  • Infrared sensor and a circuit board equipped therewith
    Patent number: 9182286
    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.

  • Infrared sensor
    Patent number: 8814426
    Abstract: An infrared sensor comprises: 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; a pair of contact electrodes, with which the first and second temperature sensor devices are attached respectively, formed on one side of the electrical insulating film sheet; an infrared absorbing film provided on the other side of the electrical insulating film sheet opposite the first temperature sensor device; and an infrared reflector film provided on the same side as the infrared absorbing film opposite the second temperature sensor device. The first and second temperature sensor devices respectively comprise: a thermistor element; and a pair of electrode layers, in which one of them is in contact with the contact electrode, formed both on the upper and lower surfaces of the thermistor element.
