PROBLEM TO BE SOLVED: To provide a filter device which can reduce the size of the device connected with a pump and simplify a production apparatus. SOLUTION: In the filter device (1) in which a connection port (3) for a pump suction port is formed in a bag body (2) formed by a mesh member (M), the connection port is formed at a position on the side of one end fringe of the bag body. In this way, a space corresponding to the height of the bag body under the pump connection port can be used effectively. A shape holding body (4) for holding the shape of the bag body is formed in the bag body, a shape holding body fixing part (7) integrated with the connection port is formed inside the bag body, and the shape holding body (4) and the shape holding body fixing part (7) are linked integrally by the engagement of projections (6) and holes (8). Accordingly, the shape holding body can be fitted to the fixing part (7) by simple manual work without needing welding equipment, or the like.
