Abstract
A culture bag for culturing adherent cells is provided without requiring a highly clean production environment and a complex production step such as a masking step. An adherent cell culture vessel that is formed of a polyolefin is configured so that part or the entirety of the inner surface of the culture vessel has a static water contact angle of 95° or more, and has an advancing contact angle and a receding contact angle that satisfy the inequality 'advancing contact angle−receding contact angle>25°' when water runs down along the inner surface.
