Thermoelectric conversion module and method of manufacturing the same

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

• preparing a honeycomb structural body made of an electrically insulating material and having a first surface, a second surface opposing 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 elements into the channels belonging to the first and second groups, respectively;
• filling spaces formed between walls defining the channels and the semiconductor elements inserted therein with electrically insulating filler members;
• cutting said honeycomb structural body into a plurality of thermoelectric conversion module main bodies of a desire shape, each of which has the N type and P type semiconductor elements provided within said channels are exposed at mutually opposing first and second surfaces;
• and
• forming metal electrodes on opposite surfaces of said thermoelectric conversion module main body 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.
