摘要： A filter device 2 is provided with: a filter body 3 equipped with a filtering material 30; and a mesh-like filter cover 5 that is mounted to the filter body 3 in such a manner as to cover at least part of a filtering surface 32 of the filtering material 30. The filter cover 5 is provided with: a purification part 50 which includes multiple layers formed by folding a single sheet of metal mesh material and which has a rectangular shape that is substantially identical to that of the filtering surface 32 in a plan view; and a first leg 51 and a second leg 52 which intersect with the purification part 50 in a side view. The metal mesh material has a finely corrugated surface formed thereon. The entire outer peripheral edge 59 of the filter cover 5 is completely fitted within the filtering surface 32.
