To improve the mass productivity of thermoelectric conversion modules. A thermoelectric conversion module 1 is equipped with a pair of substrates 11 and 12, a plurality of thermoelectric conversion elements 2, each having one end portion electrically connected to a first electrode 3 which is arranged on the substrate 11 and the other end portion electrically connected to a second electrode 4 which is arranged on the substrate 12, and a connection section 5 which electrically connects the first electrode 3 electrically connected to the thermoelectric conversion element 2 to the second electrode 4 electrically connected to an adjacent one of the thermoelectric conversion elements 2. The connection section 5 is separate from at least one of the first electrode 3 and the second electrode 4.
