Thermoelectric generation device

A thermoelectric generation device comprising:

• a first substrate that is a single-layer substrate having (i) a first surface and (ii) a cooling surface disposed opposite to the first surface in a first direction, the first substrate extending in a second direction orthogonal to the first direction;
• a second substrate spaced apart from the first substrate in the first direction, the second substrate having (i) a second surface facing the first surface and (ii) a heating surface opposite to the second surface in the first direction;
• a plurality of thermoelectric generation modules, each of which has a plurality of thermoelectric elements and electrodes connecting the thermoelectric elements, each of the plurality of thermoelectric elements being arranged between the first surface and the second surface;
• and
• a wiring that is arranged on the first surface and that connects the plurality of thermoelectric generation modules, the wiring extending in the second direction,
• wherein the first surface includes a plurality of module regions in which the plurality of thermoelectric generation modules are disposed, respectively, the plurality of module regions being spaced apart from one another in (i) the second direction and (ii) a third direction that is orthogonal to the first direction and the second direction,
• wherein the wiring includes a central wiring that extends in the second direction through a central wiring region of the first surface that separates the plurality of module regions of the first surface from one another in the third direction, and
• wherein an end portion of the central wiring symmetrically extends in the third direction and is disposed outside the plurality of module regions.
