レメント。 A hollow cylindrical body having an even polygon is formed as a whole by the filter medium 1 having a large number of continuous folds, and two parts can be divided by an imaginary plane 4 connecting the corner 2 of the polygon and the center line 3 of the cylindrical body. It is a filter element composed of two types of pleat groups A and B, and one of the two types of pleat group A starts from the pleat surface 1a along the outer peripheral surface of the polygonal cylindrical body and moves toward the center. A plurality of folds are formed at approximately equal intervals, and the other fold group B includes a plurality of folds at approximately equal intervals toward the opposing corner 2 of the polygon starting from the fold surface 1b along the virtual plane 4. These fold groups A,
A filter element formed by forming B alternately and continuously.
