Abstract
A cell culture device comprises a cell culture membrane and a substrate fixed to the cell culture membrane. The cell culture membrane is made from a thermosetting resin and has a plurality of pores that are open to at least one surface including a surface on a side that is in contact with the substrate. The substrate is made from a thermoplastic resin. In a contact region between the cell culture membrane and the substrate, part of the substrate is extended to form bulges in the pores of the cell culture membrane that are open in the contact region. This configuration suppresses reduction of the strength of the cell culture membrane and reduction of the flatness of the cell culture membrane (membrane accuracy) in the cell culture device in which the cell culture membrane and the substrate are fixed to each other.
