Container for cell administration, storage or culturing

When administering mammalian cells, or storing or culturing mammalian cells in a container, cellular adhesion to the inner surface of the container and a reduction in cell viability can be effectively inhibited by using: a container in which surfaces that come into contact with mammalian cells are formed from a fluororesin material including at least some –CF 3 terminal groups; or a container in which surfaces that come into contact with mammalian cells are formed from a fluororesin material in which the total number of non-fluorine terminal groups and –CF 2 terminal groups in the fluororesin is not more than 70 per 1 × 10 6 carbons. Using such a container makes it possible to administer, store or prepare a liquid containing mammalian cells in a high concentration and having a high portion of living cells, and contributes to regenerative medicine in which the liquid (suspension) containing mammalian cells is used.
