PROBLEM TO BE SOLVED: To provide a heat exchange ventilation device capable of lowering an indoor humidity without excessively lowering an indoor temperature. SOLUTION: This heat exchange ventilation device comprising an air supply channel for sucking the outdoor air from an outdoor-side suction port by an air supply blower and supplying the air into a room from an indoor-side blowout port through an air supply passage of a heat exchanger, and an exhaust channel for sucking the indoor air from an indoor suction port by an exhaust blower and discharging the air to the outside of the room from an outdoor-side blowout port through an exhaust passage of the heat exchanger, further comprises an outdoor temperature sensor 19c and an outdoor humidity sensor 19d disposed on the outdoor-side suction opening, detecting a temperature and a humidity of the outdoor air and outputting temperature and humidity signals, an indoor temperature sensor 20a and an indoor humidity sensor 20b disposed on the indoor-side suction opening, detecting a temperature and a humidity of the indoor air, and outputting temperature and humidity signals, and a control device controlling the air distribution amounts of the air supply blower and the exhaust blower on the basis of the output signals of the outdoor and indoor temperature sensors and the outdoor and indoor humidity sensors.
