Thermoelectric conversion device

A thermoelectric conversion device comprising:

• a base material having a first surface and a second surface facing each other in a thickness direction;
• thermoelectric conversion element arrays each having thermoelectric conversion elements lined up in a first direction among the first direction and a second direction intersecting each other in a plane on the first surface side of the base material, the thermoelectric conversion element arrays being disposed in a row in the second direction;
• first electrodes, each of which is provided at one end side of each thermoelectric conversion element constituting the thermoelectric conversion element array in the second direction and second electrodes, each of which is provided at other end side of the each thermoelectric conversion element in the second direction;
• first wirings, each of which is disposed between one thermoelectric conversion element and other thermoelectric conversion element adjacent in the first direction and electrically connected between the first electrodes or the second electrodes of the one thermoelectric conversion element and the other thermoelectric conversion element such that the thermoelectric conversion elements constituting the thermoelectric conversion element array are connected in series;
• and
• second wirings, each of which is electrically connected between the first electrodes or the second electrodes of the thermoelectric conversion elements located at one-end-most sides or other-end-most sides of one thermoelectric conversion element array and other thermoelectric conversion element array in the first direction such that thermoelectric conversion elements constituting the one thermoelectric conversion element array and thermoelectric conversion elements constituting the other thermoelectric conversion element array adjacent to the one thermoelectric conversion element array in the second direction are connected to each other in series.
