1. A cell culture device comprising:
a culture membrane including a membrane body and a support frame joined to the membrane body;
a first member including a first cylindrical portion extending in a cylindrical shape in an axial direction and a placing portion which is formed with an axial end surface facing in the axial direction, which is configured to abut against the support frame, and on which the culture membrane is placed; and
a second member including a second cylindrical portion extending in a cylindrical shape in the axial direction and a facing portion which faces the axial end surface of the placing portion in the axial direction, the facing portion and the placing portion sandwiching the support frame therebetween, wherein
the first member and the second member each have a locking portion which is configured to restrict a relative movement between the first member and the second member in the axial direction by which the first member and the second member are separated from each other in a state in which the placing portion and the facing portion are assembled to each other so as to sandwich the support frame therebetween, wherein
the first member includes a side surface opening portion which is provided so as to penetrate, in a radial direction, a predetermined portion of a peripheral wall of the first cylindrical portion including at least a part of a placing surface, on which the culture membrane is placed, of the placing portion, and which opens a part of the first cylindrical portion.
