A filter device includes a filtering member (4) having a rough part (5), which is comparatively low in a density of flow pores for flowing fluid, and a dense part (7), which is comparatively high in the density of the flow pores. The filter device further includes a support member (2, 3) that supports the filtering member (4) and has an inflow passage (31) and a discharge passage (21). The dense part (7) supports the rough part (5), and is located between the rough part (5) and the discharge passage (21), and is supported by a mechanical pressure applied by the support members (2, 3). The filter device is capable of supporting the filtering member (4) easily in a case member and securing a filtering area to enhance the performance of removing a foreign matter.
