A cell culturing apparatus and a cell culturing method are disclosed. A rack supporting apparatus includes a loop tracking and a plurality of culturing racks connected one after another in series. Each of the culturing racks accommodates culturing containers therein for cell culturing during their travel on the loop tracking. Each of the racks is accessible, through conveyors, to a container handling station where culture medium is filled in the culturing containers and cell inoculation is carried out. The culturing containers processed in the container handling station are automatically accommodated into the rack by an infeed station for starting cell culturing, and the culturing containers in which cell culturing have been performed in the rack are automatically discharged therefrom by a discharge station.
