Abstract
A classifying device that classifies aggregates and includes: a plurality of metallic porous membranes respectively including: a membrane section including a first principal surface, a second principal surface, and a plurality of through-holes. Among each of the plurality of metallic porous membranes, the through-holes have mutually different dimensions, and some of the plurality of through-holes in at least a first of the plurality of metallic porous membranes are configured to have different dimensions sufficient to release pressure applied to the first of the plurality of metallic porous membranes without degrading classification accuracy of the first of the plurality of metallic porous membranes. The plurality of metallic porous membranes are arranged in series from an upstream side of a flow path through which a liquid containing the aggregates flows in a descending order of the different dimensions of the through-holes of the plurality of metallic porous membranes.
