Abstract: In a thermoelectric conversion module, each of a p-type element and an n-type element is configured by aligning a plurality of particles in series and connecting the particles to each other. Around a connection part in which the particles are connected to each other, a protrusion is protruded. The protrusion has a shape of continuously extending around the entire periphery of the connection part. The protrusion may be partly interrupted, but in such a case, a circumferential length of one interrupted portion is less than one half of the periphery of the connection part.
