A filtration device comprising a filtration column (1) in which are installe d a filtration section (r), a liquid collecting section (7) and a liquid feedi ng section (e), the liquid feeding section (e) having a diffuser (A) mounted in an upward opening (5a) in the front end of a liquid feeding pipe (5). With t he existing installation state maintained that avoids increasing the filtration column size, and even if a filter agent of low specific gravity is used, the filtration object liquid being fed in from the opening in the liquid feeding section is applied to the filter agent in such a manner that it is distribut ed as uniformly as possible, whereby the intended filtration performance is obtained without disturbing the flatness of the upper surface of the filter agent. The diffuser (A) is provided with a deenergizing section (k) for suppressing the momentum of the liquid spouted from the opening (5a). Furthe r, a first delivery port (8) for upwardly delivering the deenergized liquid, a second delivery port (9) for laterally delivering the deenergized liquid, an d a third delivery port (10) for downwardly delivering the deenergized liquid, these delivery ports being disposed one above another in the order mentioned from top.
