A thermoelectric element ( 1 ) comprises N type thermoelectric semiconductors ( 4 ) and P type thermoelectric semiconductors ( 5 ) arranged between support members ( 2, 3 ). The N type and P type thermoelectric semiconductors ( 4, 5 ) are connected together in series by heat absorbing electrodes ( 6 ) and heat radiating electrodes ( 7 ) joined to the ends of these semiconductors. First heat transmitting members ( 8 ) are integrally provided to the heat radiating electrodes ( 7 ), and second heat transmitting members ( 9 ) are integrally provided to the heat absorbing electrodes ( 6 ) and are allowed to protrude in the same direction as (in a direction opposite to) the direction of the first heat transmitting members ( 8 ). The second heat transmitting members ( 9 ) function as heat radiating media when the thermoelectric element ( 1 ) is not in operation to dissipate the heat of a component ( 16 ) to be cooled into a radiation space via the second heat transmitting members ( 9 ).
