Thermoelectric conversion module and method of manufacturing the same

A thermoelectric conversion module, comprising:

• a plurality of p-type semiconductor blocks, each being made of a p-type thermoelectric conversion material, each having a first pillar portion and a first connection portion laterally protruding from one end portion of the first pillar portion, and each containing metal powder in the first connection portion and a different end portion of the first pillar portion;
• and
• a plurality of n-type semiconductor blocks, each being made of an n-type thermoelectric conversion material, each having a second pillar portion and a second connection portion laterally protruding from one end portion of the second pillar portion, and each containing metal powder in the second connection portion and a different end portion of the second pillar portion,
• wherein the first connection portion of each p-type semiconductor block overlaps longitudinally and is connected with the different end portion of the second pillar portion of the corresponding n-type semiconductor block, the second connection portion of each n-type semiconductor block overlaps longitudinally and is connected with the different end portion of the first pillar portion of the corresponding p-type semiconductor block, so that the plurality of p-type semiconductor blocks and the plurality of n-type semiconductor blocks are alternately connected in series.
