ように配列されている。[Claims for Utility Model Registration] A large number of rectangular filter papers that are continuous through folding ridges are erected between two parallel end plates, and the space occupied by these filter papers has a hollow cylindrical shape as a whole. A filter element in which the arrangement pattern of filter paper satisfies the following configurations (a) to (d). (b) Angle 2π/ with respect to the center line of the hollow cylinder above
n (n is an integer of 6 or more) rotationally symmetrical basic patterns are consecutive. (b) The filter papers included in one basic pattern are arranged substantially parallel to each other at substantially constant intervals. (c) The folding ridge lines on the outer circumferential side of the filter paper group are arranged at substantially equal pitches substantially along the outer circumferential circle. (d) The plurality of inner bending ridge lines on either side of the filter paper group are arranged at approximately equal pitches along the inner circumferential circle, and have approximately equal lengths that are approximately equal to the length between the inner and outer circumferential circles. In the approximately triangular cylindrical part defined by the terminal filter paper surface of this approximately equal length section and the starting end filter paper surface of the approximately equal length section of another adjacent basic pattern, the remaining plural pieces on the other side are the starting end filter paper. They are arranged so that the length becomes shorter almost along the surface.
