To provide a fine particle collection device that can collect and reduce ultra fine particles of 100 μm or less while preventing pressure drop, compared with a case in which a plate-like ventilation member composed of a honeycomb structure with the number of cells or the opening ratio per 1 square inch within a specific numerical range is not applied as collection means.SOLUTION: A fine particle collection device comprises: a vent pipe 61 that has a passage space 61a through which air including fine particles flow; and collection means 63 that is arranged to block the passage space 61a of the vent pipe 61 and collect the fine particles included in the air. The collection means 63 is formed of a plate-like ventilation member 66 that is composed of a honeycomb structure in which the number of cells 65 per 1 square inch is 600 or more and 1400 or less or a honeycomb structure in which the opening ratio per 1 square inch is 94.2% or more and 97.1% or less.SELECTED DRAWING: Figure 3 【課題】捕集手段として１平方インチ当たりのセル数又は開口率が特定の数値範囲のハニカム構造からなる板状の通気部材を適用しない場合に比べて、圧力損失を抑制しつつ１００μｍ以下の超微粒子を捕集して低減させることができる微粒子の捕集装置等を提供する。【解決手段】微粒子の捕集装置は、微粒子を含む空気が流れる流路空間６１ａを有する通気管６１と、通気管６１の流路空間６１ａ内を遮断する状態で配置され、空気に含まれる微粒子を捕集する捕集手段６３とを備え、捕集手段６３は、１平方インチ当たりのセル６５の数が６００以上かつ１４００以下のハニカム構造又は１平方インチ当たりの開口率が９４．２％以上かつ９７．１％以下のハニカム構造からなる板状の通気部材６６で構成されている。【選択図】図３
