Resins ( 5, 6 ) are interposed as insulating layers between heat radiation side and heat absorption side heat exchange bodies ( 2, 3 ) and heat radiation side and heat absorption side electrodes ( 41, 42 ) of a thermoelectric conversion element module ( 4 ). The resin ( 5 ) is fusion bonded to the heat radiation side heat exchange body ( 2 ), and the resin ( 6 ) is fusion bonded to the heat radiation side heat exchange body ( 3 ). The material of the resins ( 5, 6 ) is, for example, a thermosetting plastic. The thermosetting plastic becomes soft when heated and then cures. At the time of fusion bonding of the resins ( 5, 6 ) to the heat exchange bodies ( 2, 3 ), the heat exchange bodies ( 2, 3 ) and the resins ( 5, 6 ) are heated and pressed. Then, the resins ( 5, 6 ) become soft and enter the cavities and flaws formed in the surfaces of the heat exchange bodies ( 2, 3 ). The resins ( 5, 6 ) having entered the cavities and flaws cure to fill the cavities in the surfaces of the heat exchange bodies ( 2, 3 ).
