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.

Abstract: After a silicatizing flame, a titanium oxidizing flame, or an aluminum oxidizing flame is blown together with an oxidizing flame onto the surface of a resin base material to perform surface modification treatment, dry plating or wet plating is performed on the surface of the resin base material to thereby form a plating film. In the surface modification, in the case of the silicatizing flame, for example, silanol groups are imparted to the surface of the resin base material as polar groups necessary for obtaining adhesion to the plating film.
