A thermoelectric converter includes a first substrate, a second substrate, a plurality of thermoelectric conversion elements, and a group of electrodes. The plurality of thermoelectric conversion elements are disposed between the first substrate and the second substrate. The group of electrodes electrically interconnect the plurality of thermoelectric conversion elements. The plurality of thermoelectric conversion elements are arranged in a plurality of rows including a first row and a second row. The first row is adjacent to the second row. The group of electrodes includes a first electrode and a second electrode having a different shape from the first electrode. The second electrode includes a first notch and a second notch each of which is disposed on an edge of the second electrode. The first notch is disposed to separate one of the plurality of thermoelectric conversion elements in the first row and one of the plurality of thermoelectric conversion elements in the second row.
