摘要： A method of manufacturing a thermoelectric conversion material includes a sintering step. In the sintering step, a sintered body of a sintered material (20) is obtained by applying a voltage to a conductive mold (10) in a first direction so as to cause energization under the condition in which an insulating layer (30) is disposed in at least a portion between an inner wall (12) of the mold (10) and the sintered material (20) and the insulating layer (30) keeps having insulating properties. Here, the sintered body is a thermoelectric conversion substance.
