Thermoelectric conversion device

A thermoelectric conversion device, comprising:

• thermoelectric conversion elements that are disposed on a virtual plane;
• a plurality of first heat transfer members that are disposed on one side with respect to the thermoelectric conversion elements in a vertical direction perpendicular to the virtual plane and that are configured to transfer heat to/from the thermoelectric conversion elements;
• and
• a plurality of heat transfer parts that are disposed on an other side with respect to the thermoelectric conversion elements in the vertical direction perpendicular to the virtual plane with a space interposed therebetween in a first direction along an in-plane direction of the virtual plane, and that are configured to transfer heat to/from the thermoelectric conversion elements,
• wherein the first heat transfer members are disposed in correspondence with the heat transfer parts and are disposed to be positioned on the one side in the vertical direction opposite to the heat transfer parts,
• wherein a first low heat conduction part having lower thermal conductivity than thermal conductivity of the heat transfer parts is disposed between the heat transfer parts that are adjacent to each other in the first direction, and
• wherein a second low heat conduction part having lower thermal conductivity than thermal conductivity of the first heat transfer members is disposed between the first heat transfer members that are adjacent to each other in the first direction.
