Thermoelectric conversion module and structure for thermoelectric conversion element

A thermoelectric conversion module that has a heat reception part and a heat dissipation part, and uses a temperature difference between the heat reception part and the heat dissipation part to generate power, comprising:

• a base material having heat insulation properties;
• and
• carbon nanotube yarn that is formed in a fibrous shape from a carbon nanotube and is helically wound around the base material,
• wherein the carbon nanotube yarn includes a plurality of P-type parts formed as P-type semiconductors and a plurality of N-type parts formed as N-type semiconductors,
• the P-type parts and the N-type parts are alternately arranged and are series-connected in an extension direction of the carbon nanotube yarn,
• one side part of a helix formed by the carbon nanotube yarn is formed as the heat reception part, and the other side part across the base material from the one side part is formed as the heat dissipation part,
• lengths of the P-type parts and lengths of the N-type parts are shorter than a length of a one-turn portion of the helix, in the extension direction of the carbon nanotube yarn, and
• the P-type parts and the N-type parts are arranged such that respective one end parts are included in the heat reception part and respective other end parts are included in the heat dissipation part.
