PROBLEM TO BE SOLVED: To provide a lightweight and small-sized simple filter apparatus easily kept and carried and simple to use by providing a bag-shaped filter membrane member positioned so as to perfectly traverse a fluid passage inside a plastic bag like body having a raw soln. supply port and a filtrate outflow port provided to the upper and lower end parts thereof. SOLUTION: A plastic bag like body 1 is formed by sealing a part 2 positioned on the surface side of an inflation tube, a single layer film, pref., a laminated film and a part 3 positioned on the rear surface side thereof at both side end parts of them as shown by shaded parts to provide vertical fused parts 4, 4 in an up-and-down direction and providing the lateral fused part 5 of a bottom part without continuing to one vertical fused part 4. A liquid passage 6 is demarcated under the cooperation of the respective fused parts 4, 5, and a raw soln. supply port 7 and a filtrate outflow port 8 are demarcated to the respective upper and lower end parts. Further, a filter membrane 9 having a bag shape as a whole is arranged inside the plastic bag like body at a position perfectly traversing the liquid passage 6.
