An electrical converter and heater module with heat insulators having different cross-sectional areas includes a thermoelectric conversion module that corrects the difference in thermal resistance between a P-type thermoelectric conversion member and an N-type thermoelectric conversion member. In this thermoelectric conversion module, since insulators included in the P-type thermoelectric conversion member and the N-type thermoelectric conversion member have a different thermal resistance, it is possible to correct the difference in thermal resistance between the P-type thermoelectric conversion element and the N-type thermoelectric conversion element.

The invention provides a thermoelectric conversion element having a lot of pn junction pairs per unit area and having a thermoelectric material chip which is hardly broken, and a producing method thereof. In the thermoelectric conversion element of the invention, plural substrates in each of which a film-shaped thermoelectric material is formed in a surface thereof are disposed. As a result, because the number of pn junction pairs per unit area is increased, a high output can be obtained. Because the thermoelectric material is formed into the film shape, reliability degradation caused by a breakage of the thermoelectric material can be prevented, even in the thermoelectric material having many pn junction pairs per unit area, namely, a sectional area is small.

A surface roughness Ra of the end surfaces is larger than 0.8 micrometers. In the present invention, the thermoelectric conversion elements can be arranged at a high density such that tubes are in close adhesion to each other. Also, since the close adhesion surface of electrodes on the end surfaces is large, the connection reliability of electrodes is further improved.
