Abstract: A cell culture device includes a substrate, a wire disposed on a main surface of the substrate, an insulating film disposed on the main surface of the substrate and having a part that overlaps the wire, and the electrodes disposed on the insulating film and having a part that overlaps the wire. The insulating film has a contact hole at a position overlapping the wire and the electrode. A plurality of grooves are formed on at least the surface of a part of the electrode that overlaps the contact hole.

Abstract: A cell culture substrate includes a base, a first segment disposed on the base and occupying a part of one surface of the cell culture substrate, and a second segment disposed on the base and occupying another part of the one surface. The second segment is formed of a metal material and thus has a relatively higher surface free energy than the first segment formed of an inorganic material. The second segment is disposed such that a percentage of an area of the second segment in a total area of the first segment and the second segment increases in a gradation direction (first direction) along the one surface.
