Method of manufacturing thermoelectric conversion module

A method of manufacturing a thermoelectric conversion module comprising the steps of:

• preparing a honeycomb structural body having a first surface, a second surface opposed to said first surface, and a plurality of channels which extend from said first surface to said second surface, alternate one or more of said channels being classified into a first group and the remaining channels being classified into a second group;
• inserting N type and P type semiconductor strips into the channels belonging to the first and second groups, respectively;
• filling spaces formed between walls defining the channels and the semiconductor, strips inserted therein with filler members;
• cutting said honeycomb structural body into a plurality of thermoelectric conversion module main bodies, each of the bodies having N type and P type semiconductor elements provided within said channels exposed at mutually opposing first and second surfaces;
• forming metal electrodes on opposite surfaces of said each of the bodies such that adjacent one or more N type semiconductor elements and one or more P type semiconductor elements are connected in cascade by means of said metal electrodes;
• and
• removing said filler members or said honeycomb structural body and filler members.
