Zusammenfassung:A minute-particle trapping device includes: an air duct having a duct space through which air containing minute particles flows; a first filter disposed to block the duct space in the air duct and having a honeycomb structure to trap the minute particles contained in the air; and a second filter disposed in the air duct at a position downstream from the first filter in an air flow direction to block the duct space, the second filter being formed from a nonwoven fabric folded in a wave pattern to trap minute particles contained in the air that has passed through the first filter.
