<p>PURPOSE: A dehumidification device using thermoelectric element is provided to heat-exchange air with a cooling plate by selectively supplying the air to the cooling plate according to the temperature of the cooling plate, thereby increasing dehumidification efficiency. CONSTITUTION: A dehumidification device using thermoelectric element comprises a damper(150), a damper operating member(160), and a return unit(170). The damper operating member has a temperature detecting part to detect the temperature of a cooling plate. If the cooling plate is frozen when the temperature of the cooling plate detected in the temperature detecting part is decreased under a pre-set temperature, the damper operating member opens the damper to flow the air into a second space part. In order to prevent the inflow of air into the second space part, the damper operating member repeats a motion to close the damper when the temperature of the cooling plate is risen up again. The return unit is formed to communicate the second space part with a first space part so that the heat-exchanged air can be recirculated to the first space part.
