Abstract
A thermoelectric conversion module having a large capacity and a curved surface is manufactured by immersing a honeycomb structural body having a number of through holes, openings of every other through holes being closed by clogging members, into a semiconductor material melt of one conductivity type to suck the semiconductor material melt into through holes whose openings are not closed, cooling the thus sucked semiconductor material melt to form semiconductor elements of one conductivity type, immersing again the honeycomb structural body after removing said clogging members into a semiconductor material melt of the other conductivity type to suck the semiconductor material melt into the through holes, cooling the thus sucked semiconductor material melt to form semiconductor elements of the other conductivity type, cutting the honeycomb structural body into a plurality of thermoelectric conversion module main bodies, and providing metal electrodes of both surfaces of a thermoelectric conversion module main body such that alternate semiconductor elements of one and the other conductivity types are connected in series.
