摘要： A thermoelectric device includes a thermoelectric element composed of principally thermoelectric material, a counter element adhered to the thermoelectric material. A solder layer lies between the thermoelectric element and the counter element and adheres the thermoelectric element to the counter element. A restraining layer prevents the solder ingredient of the solder layer from spreading into the thermoelectric element. The restraining layer is composed of a first layer to prevent the solder ingredient of the solder layer from spreading into the thermoelectric element and a second layer composed of material having a higher wetting property than the first layer with respect to the solder layer.
