NOVELTY - The conversion element has a laminate structure and electrodes. The laminate structure has several p-type silicide substrates (1) and n-type silicide substrates (2) that are alternately laminated with each other. The laminate structure has adhesive layers that adhere with p-type silicide substrate and n-type silicide substrate adjacent to each other and comprise a cured matter of inorganic adhesive (3) with a mixture of inorganic binder and filler. The electrode is formed on laminate structure and electrically connects silicide substrates in series.    USE - Thermoelectric conversion element for use at high operation temperature in automobile. Can also be used in recovering heat generated in internal combustion engine of automobile or recovering exhaust heat in industrial furnaces, incinerators and small-scale thermal power stations in industries.    ADVANTAGE - The deterioration of generation efficiency of the thermoelectric conversion element over time is reduced. The high temperature difference is maintained in the thermoelectric conversion element by inorganic adhesive and the deterioration of the insulation and thermal conduction properties over time is reduced. The evaporation of water content during the curing of the inorganic adhesive is facilitated, the foaming and reaction with the binder content to generate non-aqueous compound is prevented by the filler, hence the water resistance, anti-corrosion property of the substrate against the binder, adhesive strength, heat resistance, electrical properties, anti-humidity and anti-drug property are improved. The cracks and fractures of the substrates are prevented. The thermoelectric efficiency is improved.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a thermoelectric conversion module; and    (2) a method of producing a thermoelectric conversion element.    DESCRIPTION OF DRAWING(S) - The drawing shows the perspective views of the substrate and an exploded perspective view of the thermoelectric conversion element.
