A so-called corrugated cardboard structure in which layers are stacked is commonly used. Various types of waveforms are known, such as sinusoidal and triangular shapes, and methods for forming waveforms include using a plate-like material (e.g., paper, metal foil, etc.) between the main gear and the driven gear. Various methods are known, including a method of forming a sheet into a tooth shape through a sheet or film made of synthetic resin or nonwoven fabric (the same applies hereinafter), or a method of shaping using a folding machine.

術もある。When assembling the corrugated members obtained in this manner to produce a filter, for example, US Pat. No. 3,020,
As seen in No. 977, after a corrugated member alone or a combination of the corrugated member and a flat plate material to form an aggregate, one end side of the sheet edge in the direction perpendicular to the corrugation (hereinafter referred to as the longitudinal direction) Adjacent small holes are alternately closed and arranged so that the open ends and closed ends are alternately lined up, and on the other end side, the end of the small hole opened on the -Manzu side is closed, and the end of the small hole opened on the -Manzu side is closed. A device has been developed in which the small hole is closed and the end is open. With this configuration, the fluid introduced from the end side cannot flow away in the longitudinal direction as it is, so it passes through the corrugated member and enters the adjacent passage before being released from the opening at the other end. Therefore, filtration is performed during the permeation process. Also, Japanese Patent Publication No. 61-59775 and Japanese Patent Publication No. 58-219
As seen in Japanese Patent No. 921, there is also a technique in which a fluid is caused to flow parallel to a corrugated member and deodorization, ozone decomposition, etc. are performed using a catalyst such as activated carbon contained or attached to the surface of the corrugated member.
