とを特徴とするフイルタエレメント。 A large number of rectangular filter papers that are continuous through the inner and outer folded edges are arranged in a dense manner so as to extend approximately in the radial direction between the inner porous cylinder arranged concentrically and the virtual outer circumferential circle. In a filter element in which the space occupied by these filter papers has an annular shape as a whole, the annular region is substantially rectangular in plan view, and first filter element regions are arranged at substantially equal intervals in terms of angle. ,
and a substantially triangular second filter element area disposed between adjacent first filter element areas, and in the first filter element area, each filter paper extends from the virtual outer circumferential circle to the inner porous cylindrical body. In the second region, the filter paper at the center extends from the virtual outer circumference to the vicinity of the inner porous cylindrical body. A filter element characterized in that the filter papers on both sides of the central filter paper are arranged in such a manner that their inner folded ridge lines do not reach the inner porous cylindrical body.
