くなればなる程その傾向も増大するという問題点
があつた。 However, in the case of the former, since the filtration holes are pointwise, the filtration area is small, and therefore the clogging phenomenon is large, which is a disadvantage, and this tendency increases as the filtration particle size becomes smaller. It was hot.

ならないという問題点があつた。 In the latter case, the porous structure forces steric filtration, and impermeable foreign matter grows and clogs the porous structure, unavoidably reducing the filtration rate. Therefore, there is a problem in that foreign matter within the porous structure must be completely removed by frequent cleaning or the like.

状素子を特願昭62−96198号において提案した。 In order to solve this problem, the present inventor used a long wire rod with a desired cross-sectional shape, wound it in a spiral shape and also in a conical shape, and created a spiral shape between the peripheries of adjacent wire rods. A patent application filed in 1982 provides a conical element for filtration or separation in which a slit hole is formed to maximize the filtration or separation processing area as a so-called linear processing hole, thereby improving the filtration or separation effect. Proposed in No. 96198.
