A cell culture apparatus is provided which can continuously and accurately measure turbidity of a cell culture solution and culture a cell, without inserting a turbidity sensor from outside into a sterile bag. The cell culture apparatus (1) includes: a flexible and transparent sterile bag (2) that is installed at a prescribed position in the cell culture apparatus and in which a cell contained in a cell culture solution (4) is cultured; and a turbidity sensor (3) that includes a light emitter (31) which emits light to the cell culture solution (4) in the sterile bag (2) via a portion (2a) of the sterile bag (2), a light receiver (32) which receives the light transmitted through the cell culture solution (4) via another portion (2b) of the sterile bag (2), and that is configured to place the light emitter (31), the portion (2a) of the sterile bag (2), another portion (2b) of the sterile bag (2), and the light receiver (32), optically on a same straight line. |
