To provide a compact ventilation device having small circulation resistance and capable significantly reducing pressure loss.
This ventilation device (10) comprises a casing (20) provided with an outdoor air suction port (21), an indoor air suction port (22), and an air supply port (23), and an air distribution fan (30) received in the casing (20). The ventilation device (10) sucks the outdoor air and the indoor air from the suction ports (21, 22) into the casing (20) by the air distribution fan (30), processes the sucked air, and supplies the processed air indoors from the supply opening (23). An electric dust collecting unit (40) is disposed in the casing (20) to remove dust in the sucked air. Further a deodorizing unit (50) of low circulation resistance, is disposed in the casing (20) to remove odor substances in the sucked air.
