Abstract
A thermoelectric conversion element, a thermoelectric conversion module, and a method for producing a thermoelectric conversion element are provided, each of the element and the module having a low contact resistance between a p-type thermoelectric conversion material and an n-type thermoelectric conversion material and being capable of being used at high temperatures without deterioration due to oxidation. A p-type oxide thermoelectric conversion material is primarily made of a substance having a layered perovskite structure represented by the formula: ABO, wherein A includes at least La, and B represents at least one element including at least Cu. An n-type oxide thermoelectric conversion material is primarily made of a substance having a layered perovskite structure represented by the formula: DEO, wherein D includes at least one of Pr, Nd, Sm, and Gd, and E represents at least one element including at least Cu. The p-type oxide thermoelectric conversion material, the n-type oxide thermoelectric conversion material, and a composite insulating material are co-sintered. A glass having a softening point of about 550° C. to about 750° C. is used as a glass defining the composite insulating material.
