ABSTRACT A filtration apparatus for removing undesirable components from a solution to be treated, comprising a module in which a number of hollow fibers fixed at one end thereof by cast-molding materials, opened at the end portion above described and closed at another end portion thereof, in which said solution to be treated can definitely be kept from leaking out of a mechani- cally sealed portion. Also, any defect in said sealed portion can be detected from the outside by leading the leaked solution to the outside of the apparatus even if the defects were in said mechanically sealed portion. This apparatus is preferably used for the manufacture of purified water free from bacteria, pyrogene and the like. Ultra-purified water of remarkably high purity can be obtained when it is used as a check filter in a process for manufacturing ultra-purified water.
