Abstract
In an infrared sensor () having a bolometer element () and a reference element (), the reference element () comprises a bolometer film (), a substrate-side insulating film () formed on the substrate-side surface of the bolometer film (), a heat dissipation film () made of amorphous silicon formed on the substrate-side surface of the bolometer film () with the substrate-side insulating film () interposed therebetween, and a plurality of heat dissipation columns () made of amorphous silicon thermally connected to the heat dissipation film () and a substrate (), while the bolometer film () and substrate-side insulating film () are formed such as to extend over a side face of the heat dissipation film () intersecting a surface of the substrate (). Thus configured infrared sensor () can efficiently reduce the influence of temperature changes in the environment in use, while being made smaller.
