To suppress occurrence of dew condensation on a filter for capturing dust contained in sucked air.SOLUTION: A ventilation device includes: a ventilation air passage 5; and a circulation air passage 6 for circulating a part of the air passing the ventilation air passage 5. The circulation air passage 6 includes: a circulation air opening part 9 for communicating with the ventilation air passage 5; and a filter 10 for capturing dust contained in the air passing the circulation air passage 6. The circulation air opening part 9 is positioned on a wall surface of the ventilation air passage 5, and the filter 10 covers the circulation air opening part 9. With this constitution, the ventilation device can be acquired in which contact between the filter 10 and the air passing the ventilation air passage 5 during a ventilation operation is suppressed, and in which occurrence of dew condensation on the filter 10 is suppressed.SELECTED DRAWING: Figure 1 【課題】吸込む空気に含まれる塵埃を捕集するフィルターに結露が発生することを抑制することを目的とする。【解決手段】換気風路５と、換気風路５を通る空気の一部を循環するための循環風路６と、を備え、循環風路６は、換気風路５と連通する循環風開口部９と、循環風路６を通る空気に含まれる塵埃を捕集するフィルター１０と、を備え、循環風開口部９は、換気風路５の壁面に位置し、フィルター１０は、循環風開口部９を覆うという構成にしたことにより、換気運転の際にフィルター１０と換気風路５を通る空気との接触を抑制し、フィルター１０に結露が発生することを抑制した換気装置を得られる。【選択図】図１
