Abstract
In the reference element employed in the thermal-type infrared solid-state image sensing device according to the present invention, a slit used for construction of a light receiving element is opened in insulating films between which a thermoelectric conversion element is tucked to such an extent that the slit pierces into the sacrifice layer; a film made of electrically conductive material covering the light receiving section and the slit is provided and a protective film is provided thereon, and the film made of electrically conductive material and the protective film enter the interior of the slit along a side wall of the slit, whereby a void is left in the interior of the slit. As a result, residual stresses of the insulating films are kept equal in the light receiving element and the reference element, and thereby, the light blocking effect and the heat transfer effect are improved.
