Abstract
A polyurethane porous membrane is produced by a simple method to be used for at least one of applications of cell culture and cancer cell growth inhibition. The production method of the polyurethane porous membrane to be used for at least one of the applications of cell culture and cancer cell growth inhibition comprises: a first step of forming a layer of a polyurethane material which is uncured, on a substrate; and a second step of supplying water vapor to an exposed surface of the layer of the polyurethane material formed on the substrate, which is away from the substrate, so as to cure the polyurethane material and provide the layer of the polyurethane material with a porous structure having a plurality of irregularities on the exposed surface.
