Abstract
An improved thermopile is provided. A plurality of thermocouples constituting the thermopile are composed of segments of one metal and segments of the other metal, and the segments of different metals are connected to one another alternately so that the thermocouples are arranged in series on a heat-resistant, electrically non-conductive substrate. Each segment has a portion plated on one surface of the substrate, a portion plated on the other surface of the substrate and a portion plated on the inner wall of through holes formed in the substrate to connect the two portions plated on the two surfaces of the substrate with each other. The thermopile is prepared advantageously by utilizing plating and photo-etching techniques.
