Abstract
A thermoelectric conversion component includes a substrate having a cavity. An insulating film is formed on the upper surface of the substrate. A small heat-capacity region is formed in the center of the insulating film, and a large heat-capacity region is formed in the outer peripheral portions of the substrate and the insulating film. A thermoelectric pattern is formed on the upper surface of the insulating film so that hot junctions and cold junctions are respectively placed on the small heat-capacity region and the large heat-capacity region. Thermosensitive resistor patterns are formed on the outer peripheries of the cold junctions of the thermoelectric pattern.
Claims3
A thermoelectric conversion component comprising:
