Abstract
A filter is composed of a filter member forming at least two opposed faces, an inner space surrounded by the filter member for accumulation of a liquid, and a coupling member establishing communication between the inner space and the outside to discharge the liquid in the inner space to the outside. The liquid flows through the filter member, is thereby removed of foreign matters, and is discharged via the coupling member. Convexo-concaves are provided on at least one face of the filter member.
