NOVELTY - Thermoelectric conversion module (1) comprises many layered planar bodies (7). Each of the layered planar bodies includes: a base material (10) having a planar shape, many p-type granular bodies (11) made of a p-type thermoelectric material, and many n-type granular bodies (12) made of an n-type thermoelectric material. The p-type granular bodies and the n-type granular bodies are held by the base material in such a manner as to be spaced apart from each other in a direction along a face of the base material crossing a layered direction of the layered planar bodies.    USE - The thermoelectric conversion module is useful for performing thermoelectric power generation by the Seebeck effect and/or thermoelectric cooling (electronic cooling) by the Peltier effect.    ADVANTAGE - The thermoelectric conversion module: is manufactured far more easily with improved productivity; provides easy handling of the planar bodies because the planar bodies are far larger than the granular bodies; and exhibits improved durability against shock and/or vibration.    DETAILED DESCRIPTION - Thermoelectric conversion module comprises many layered planar bodies. Each of the layered planar bodies includes: a base material having a planar shape, many p-type granular bodies made of a p-type thermoelectric material, and many n-type granular bodies made of an n-type thermoelectric material. The p-type granular bodies and the n-type granular bodies are held by the base material in such a manner as to be spaced apart from each other in a direction along a face of the base material crossing a layered direction of the layered planar bodies. The p-type granular bodies in a first planar body from among the layered planar bodies are electrically connected to the p-type granular bodies in at least one second planar body adjacent to the first planar body, and the p-type granular bodies in the layered planar bodies are thus connected in series to each other to constitute many sets of p-type elements. The n-type granular bodies in the first planar body are electrically connected to the n-type granular bodies in the adjacent at least one second planar body, and the n-type granular bodies in the layered planar bodies are thus connected in series to each other to constitute many sets of n-type elements. The planar bodies arranged at both ends in the layered direction of the layered planar bodies include the p-type granular bodies and the n-type granular bodies electrically connected to each other, to thus form a series connection in which the p-type elements and the n-type elements alternate with each other.
