In the production of a culture vessel in which a low cell-adhesive polymer as a coating agent is applied to a culture surface having a plurality of concave parts formed thereon, a use amount of the coating agent can be reduced. The low cell-adhesive polymer as the coating agent is applied to a surface of a culture base material in advance, and subsequently the culture base material is subjected to processing to form the culture vessel having the surface of the culture base material coated with the coating agent as the culture surface.

Method for producing culture vessel, and culture vessel

Provided is a culture container base material made of a polyolefin material, capable of readily forming a culture container for culturing adherent cells. The culture container base material is for culturing the adherent cells and made of the polyolefin material. At least a part of a surface of the base material is subjected to a surface treatment, where the surface of the base material is a culture surface of the culture container, and the surface subjected to the surface treatment has a static water contact angle of greater than 80° and a receding contact angle of less than 53°.
