Abstract
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 includes: a flexible and transparent sterile bag that is installed at a prescribed position in the cell culture apparatus and in which a cell contained in a cell culture solution is cultured; and a turbidity sensor that includes a light emitter which emits light to the cell culture solution in the sterile bag via a portion of the sterile bag, a light receiver which receives the light transmitted through the cell culture solution via another portion of the sterile bag, and that is configured to place the light emitter, the portion of the sterile bag, another portion of the sterile bag, and the light receiver, optically on a same straight line.
