In a liquid feeder and a cell culture apparatus provided therewith, a feed pipeis connected with a gas bag, the liquid to be fed into the feed pipeis fed so as to be sandwiched by a gas for suppressing the qualitative changes of the liquid. Furthermore, the gas bag is connected with a containerfor holding a liquid, and holds the gas for suppressing qualitative changes of the liquid in a gas phase of the container.
