An infrared sensor includes a substrate including an insulating layer formed thereon, a thermoelectric conversion element mounted on the substrate through the insulating layer, and an infrared absorbing layer mounted on the thermoelectric conversion element. The thermoelectric conversion element includes at least one single element having a heating surface defined as one side face and a cooling surface defined as the opposite face of the heating surface, for generating an electric power from the temperature difference made between the heating surface and the cooling surface. The single element includes a sintered cell including a composite metallic oxide, a pair of electrodes formed on the heating surface and the cooling surface of the sintered cell, and lead wires connecting the electrode on the heating surface and the electrode on the cooling surface electrically in series.
