A cell culture device comprises a first inner cylinder formed in a tubular shape, a cell culture membrane placed to cover over an entire one end of the first inner cylinder and configured to be folded down toward an outer surface of the first inner cylinder along an outer circumference at the one end of the first inner cylinder, and an outer cylinder formed in a tubular shape, configured to place the first inner cylinder inside thereof such that a height direction of the outer cylinder is identical with a height direction of the first inner cylinder, and provided with a first slit in an area overlapping with at least the one end of the first inner cylinder to be extended in the height direction, wherein the cell culture membrane is held between an inner wall surface of the outer cylinder and the outer surface of the first inner cylinder.

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.
