Abstract:
1. A thermoelectric conversion element comprising: a p-type oxide thermoelectric conversion material and an n-type oxide thermoelectric conversion material; wherein the p-type oxide thermoelectric conversion material is directly bonded to the n-type oxide thermoelectric conversion material in one region of a junction surface between the p-type oxide thermoelectric conversion material and the n-type oxide thermoelectric conversion material; the p-type oxide thermoelectric conversion material is bonded to the n-type oxide thermoelectric conversion material with an insulating material provided therebetween in another region of the junction surface; the p-type oxide thermoelectric conversion material, the n-type oxide thermoelectric conversion material, and the insulating material are co-sintered; the insulating material includes Li the glass has a softening point of about 550° C. to about 750° C.; the p-type oxide thermoelectric conversion material is primarily made of a substance having a layered perovskite structure represented by the formula: A the n-type oxide thermoelectric conversion material is primarily made of a substance having a layered perovskite structure represented by the formula: D
