When a size is increased for mass production, an area of a pressurized surface is increased. This raised a problem in that insufficient load or the like causes a pressure during pressure sintering and a relative density of a thermoelectric conversion element to be likely to become insufficient. As a solution, there is provided a method for producing a thermoelectric conversion element, including: a step of mixing a skutterudite-type thermoelectric conversion material powder containing Sb and a sintering agent containing a compound including Mn and Sb, to obtain a mixture; and a step of sintering the mixture.

Method for producing thermoelectric conversion element

This method is for manufacturing a thermoelectric conversion module in which a first conductive member, a thermoelectric conversion element, a second conductive member are joined by joining members, the method comprising: a step for, after applying on the first conductive member a first paste including metal particles, disposing the thermoelectric conversion element on the first paste, and compressing and spreading the first paste; a step for disposing the second conductive member, after applying a second paste including metal particles in a controlled amount, on the thermoelectric conversion element, and compressing and spreading the second paste; and a step for sintering the first and the second pastes to obtain joining members.
