Abstract: A thermoelectric module includesa plurality of electrodes (high temperature side electrodes and low temperature side electrodes, thermoelectric conversion elements (p-type element and n-type element) arranged between the two electrodes, and a bonding layer disposed between the electrodes and the thermoelectric conversion elements. The bonding layer includes copper-containing particles, copper balls each having a particle diameter of 30 ?m or more, an intermetallic compound of copper and tin, and a fired resin.

Abstract: A thermoelectric module 1 includes: a plurality of electrodes (high temperature side electrodes 11 and low temperature side electrodes 12); thermoelectric conversion elements (p-type element 21 and n-type element 22) arranged between the two electrodes; and a bonding layer 30 disposed between the electrodes and the thermoelectric conversion elements. The bonding layer 30 contains copper-containing particles, copper balls each having a particle diameter of 30 ?m or more, an intermetallic compound of copper and tin, and a fired resin.

Abstract: A composition includes metal particles capable of transient liquid phase sintering and a thermoplastic resin having a thermal decomposition rate of 2.0% by mass or less, the thermal decomposition rate being measured under a nitrogen stream using a thermogravimetric measurement device.

Abstract: A method of producing a joined body includes: providing a composition for transient liquid phase sintering to at least one of a portion of a first member to which a second member is to be joined and a portion of the second member to which the first member is to be joined, so as to form a composition layer; bringing the portion of the first member to which the second member is to be joined and the portion of the second member to which the first member is to be joined into contact with each other via the composition layer; and sintering the composition layer by heating, and the composition for transient liquid phase sintering includes metal particles capable of transient liquid phase sintering and a thermoplastic resin.

Abstract: A composition includes metal particles capable of transient liquid phase sintering and a polyamide imide resin.

Abstract: A composition includes metal particles capable of transient liquid phase sintering and a thermoplastic resin having a softening point that is lower than the liquid phase transition temperature of the metal particles.

Abstract: A bonding material disclosed in this specification contains high melting point metal particles, low melting point metal particles, and a thermosetting flux resin. A mass proportion of the high melting point metal particles with respect to a total mass of the high melting point metal particles and the low melting point metal particles is 55% to 75%.
