A thermoelectric conversion module includes an insulative substrate, a plurality of thermoelectric conversion material films disposed with a gap therebetween on a first surface of the insulative substrate and made of any one of an n-type thermoelectric conversion material and a p-type thermoelectric conversion material, a first electrode and a second electrode, formed away from each other on each of the thermoelectric conversion material films, a first thermal conduction member disposed on a side of the first surface of the insulative substrate and including a protruding portion in contact with the first, electrodes or the insulative substrate between the first electrodes, and a second thermal conduction member disposed on a side of a second surface of the insulative substrate and including a protruding portion in contact with the second surface of the insulative substrate at an area coinciding with the second electrodes.
