Thermopile has a plurality of reference junctions and a plurality of measurement thermocouple junctions connected electrically alternately in series on a dielectric support. Each reference junction has thereover a first medium which is nonthermally responsive and each measurement junction has thereover a second medium which is thermally responsive. The first and second mediums occupy areas which are arranged in a checkerboard pattern, the reference junctions under areas occupied by said first medium each being electrically connected directly to a measurement thermocouple under an area occupied by said second medium.
