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 μm or more, an intermetallic compound of copper and tin, and a fired resin.
