CULTURE CONTAINER FOR ADHERENT CELLS AND METHOD FOR PRODUCING CULTURE CONTAINER FOR ADHERENT CELLS

摘要

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. It is preferable that the polyolefin include an antioxidant (particularly preferably a phenol-based antioxidant). An adherent cell culture vessel that has a culture surface having a contact angle and a hysteresis within the above ranges may be obtained by applying UV rays having a wavelength other than an ozone-generating wavelength to a polyolefin.
