To provide an air conditioner using a thermoelectric module capable of feeding cooling heating air individually comfortable to a user.

The air conditioner comprises the thermoelectric module 100 having a high temperature part to radiate heat by an electric power and a low temperature part to absorb heat; a heat absorption promoting means 200 thermally coupled to the low temperature part 120 of the thermoelectric module 100 and promoting heat exchange with the low temperature part 120 and air; and a radiation promoting means 300 coupled to the high temperature part 110 of the thermoelectric module 100 and cooling the high temperature part by promoting heat exchange of the high temperature part 110 and air.
