(JP9329058-A)      The thermoelectric generator has structure which includes a thermoelectric element or a planar electric generation unit comprising thermoelectric elements held between thermal input part and the heat radiation part, fuel gas supply device, and device for mixing fuel gas with air. The combustion heat can be directly supplied to the thermoelectric element by burning the mixed gas of the fuel with air in catalyst part having a heat conductive end plate and a catalyst part which are in contact with the thermoelectric element.    The face opposite to the thermoelectric element of the heat conductive end plate have convex and concave configuration, and the catalyst part is made in the convex and concave configured surface. The catalyst part is a metal carried catalyst made by coating ceramic fine powder carried with precious metal catalyst on the surface of heat resistant metal thin plate with thickness not more than 0,5 cm. The metal carried catalyst is in the form covering at least part of the convex and concave shape.    ADVANTAGE -   Output of heat generator can be suppressed and safety can be secured.
