  • Patent number: 10631371
    Abstract: A heater includes an elongated substrate, a heating resistor formed on the substrate, a resistor electrode that is formed and is in contact with the heating resistor, and a heat conducting film. The substrate includes a heat generating section and a non-heat generating section. The heat generating section is a section that is overlapped with, out of the heating resistor and the resistor electrode, only the heating resistor in the lengthwise direction of the substrate. The non-heat generating section is a section that is different from the heat generating section and is adjacent to the heat generating section in the lengthwise direction of the substrate. The heat conducting film is formed so as to extend from the heat generating section into the non-heat generating section on the substrate.
