1. An infrared detection device comprising:

  • a substrate provided with a recess and including a frame positioned around the recess; and

    a heat-type light sensing element including a sensing unit and a leg connected onto the frame so that the sensor unit is positioned over the recess, the heat-type light sensing element also including an intermediate layer provided on the substrate, a first electrode layer provided on the intermediate layer, a sensing layer provided on the first electrode layer, and a second electrode layer provided on the sensing layer,wherein the substrate has a linear thermal expansion coefficient larger than a linear thermal expansion coefficient of the sensing layer, andwherein the intermediate layer has a linear thermal expansion coefficient decreasing toward the first electrode layer from the substrate.
