Abstract
An aeration module capable of aerating a liquid supplied to inner portions of hollow-fiber membranes includes a housing containing a fluororesin as a main component, and a plurality of the hollow-fiber membranes containing polytetrafluoroethylene or a modified polytetrafluoroethylene as a main component. A porosity K [%], an average thickness T[mm], and an average outer diameter D[mm] of the hollow-fiber membranes satisfy a relation of a formula of K/(T×D×100)≥2.0.
