PROBLEM TO BE SOLVED: To provide a ventilation device for mushroom cultivation facilities, particularly relating to improvement in an outside air-introducing mechanism and reducing air conditioning cost for the mushroom cultivation facilities. SOLUTION: The ventilation device for mushroom cultivation facilities 20 includes: a total heat exchanger 28 for discharging inside air in mushroom cultivation facilities 10 to the outside, introducing the outside air, and also conducting total heat exchange of the inside air and the outside air; an outside air directly introducing path 24 introducing the outside air into the inside of the facilities without passing through the total heat exchanger 28; an introducing path switch 30 for switching between a heat exchange outside air introducing path 26 passing through the total heat exchanger, and the outside air directly introducing path 24; and a controller 32 for instructing the introducing path switch 30 to switch to the outside air directly introducing path 24 when the outside air temperature is lower than the target temperature of the inside air in the facilities and the inside air temperature in the facilities is higher than the target temperature of the inside air in the facilities, instructing the introducing path switch 30 to switch to the heat exchange outside air introducing path 26 when the outside air temperature is higher than the target temperature of the inside air in the facilities, and instructing the introducing path switch 30 to switch to the heat exchange outside air introducing path 26 when the temperature of the inside air in the facilities is lower than the target temperature of the inside air in the facilities.
