A dehumidifying apparatus with an electronic refrigeration unit includes a thermoelectric unit, a DC power source, and absorbing and liberating heat exchangers. The thermoelectric unit includes a plurality of N-type thermoelectric elements, heat absorbing electrodes, P-type thermoelectric elements, and heat liberating electrodes electrically connected in series. The DC power source supplies DC current to the N-type and P-type thermoelectric elements serially connected through the heat absorbing and heat liberating electrodes. The absorbing and liberating heat exchanger are integrated with the heat absorbing and liberating electrodes, respectively. A heat liberating surface of the liberating heat exchanger is formed at a position different from the absorbing heat exchanger. The absorbing and liberating heat exchangers include heat absorbing and liberating fins, respectively. A notch is formed in one side of each of the heat liberating fins so that a part of a heat absorbing fin fits the notch. The heat absorbing fins are set in a position corresponding to a notch of a corresponding heat liberating fin so that a part of the heat absorbing fin overlaps a part of the heat liberating fin. The overlapped portions are used for the heat absorbing and heat liberating electrodes.
