The oxygen-enriched membrane device has a plurality of oxygen-enriched membranes arranged in parallel with a space between each other, and the primary side to the secondary side of the oxygen-enriched membrane that easily allows oxygen to permeate when fresh air is passed through the space. Oxygen is permeated by a pressure difference created by a vacuum pump (not shown) into the space to generate air with an increased oxygen concentration. The oxygen high-concentration air is provided from the take-out port 1A to the indoor space via the indoor unit by a vacuum pump. The oxygen low-concentration air that has passed through the primary side without passing through the oxygen-enriched membrane flows out of the oxygen-enriched membrane device 1 and mixes with surrounding air. Fresh air is allowed to flow in from one of the four sides of the structure in which flat oxygen enriched membranes are stacked with a space, and the air that has passed through the primary surface of the membrane is allowed to flow out from the remaining three sides. Efficient oxygen high-concentration air can be obtained by using the configuration.
