Abstract
In the cell culture device, a volume of a space defined by a diaphragm of the diaphragm pump and a plane at an outer edge of the diaphragm is 1 cmor more and 20 cmor less, in a case where an angle formed by a straight line connecting a foot of a perpendicular line from the apex to the plane to each point in the diaphragm and by the perpendicular line is denoted by an angle A, a thickness H of the diaphragm is within a range of 0.5 mm or more and 1.5 mm or less where the angle A is from 0° to 75°, and in a case where a thickness of the diaphragm at the apex is denoted by H, the thickness H satisfies a relationship of 1≤H/H≤1.75 at any point where the angle A is from 0° to 75°.
