Summary:A ventilation system includes an inside air passage (P1) that has an inflow end and an outflow end that each communicate with an indoor space (R) to be ventilated; at least one permeable film unit (30) that includes a permeable film (35) which allows a target gas to pass therethrough and which allows the target gas that has passed through the permeable film (35) to be discharged into outdoor air, the target gas containing at least one of carbon dioxide and a volatile organic compound in indoor air that flows in the inside air passage (P1); and an air supply passage (P3) that has an inflow end which communicates with an outdoor space (O) and an outflow end which is connected to a downstream side of the permeable film (35) in the inside air passage (P1).
