摘要

PROBLEM TO BE SOLVED: To provide a porous body that makes productivity proper and makes flow resistance of a filtration fluid low, by increasing a product yield and simplifying a manufacturing process.SOLUTION: In a porous body 6, a plurality of fluid flow passage holes 3, which pass between a pair of opposed surfaces 6a and 6b and which guide a fluid to be treated, and a slit 5, which is at least partially closed along the fluid flow passage holes 3 and formed to be opened on a side surface 6c, are formed. The slit 5 is partitioned and formed so as to equally disperse the plurality of fluid flow passage holes 3.
