Claims

[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). (a)...A plurality of filter paper groups that are rotationally symmetrical with respect to the center line of the hollow cylinder constitute the same pattern. (b)...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. (c) The above group of filter papers has a plurality of pieces located in the center, and the folded ridge line on the inner circumference side is arranged at approximately equal pitches along the inner circumferential circle, and a substantially equal length section, and on both sides of this equal length section. It consists of a connecting part between consecutive groups of filter papers. (d) The connecting portion has an inner circumferential fold curve on the radial line within a substantially triangular cylindrical portion defined by a starting end filter paper of a substantially equal length portion and a terminal end filter paper of a substantially equal length portion of another filter paper group adjacent in the circumferential direction. and are arranged so as to become shorter toward the outer circumference.
