PROBLEM TO BE SOLVED: To provide a filtration arrangement preventing a deflection deformation of a filter element by a liquid pressure and excellent in a sealing property of an end part of the filter element. SOLUTION: The present invention relates to the filtration device which is provided with a casing partitioned to an upper chamber 10b and a lower chamber 10a by a partition plate 20, and a plurality of tube-like filter elements 50 which are arranged in the lower chamber and of which an upper end is joined to a communication hole 20a of the partition plate 20; and in which a treating liquid C introduced to the lower chamber 10a is permeated through a peripheral wall part of the filter element 50, is filtered, is passed through the inside of the filter element and the communication hole 20a and is led to the upper chamber 10b. The intermediate support plates 41-43 provided with support holes 41a-43a are supported to the casing 10 through a support shaft 5 in the state that a vertical midway area of the filter element 50 is inserted and supported in the support holes 41a-43a.
