applying a low cell-adhesion polymer as a coating agent to a surface of a culture base material in advance; and
subsequently processing the culture base material to form a culture vessel having the surface of the culture base material coated with the coating agent as a culture surface, wherein,
in the processing, a plurality of concave parts are formed on the surface of the culture base material by concave-convex processing, and the processed surface is used as the culture surface of the culture vessel.
