PROBLEM TO BE SOLVED: To hold a membrane for cell culture with sufficiently high reliability while requirement to dimensional accuracy of constituent members is suppressed.SOLUTION: A cell culture tool comprises a cylindrical first internal cylinder. Further, the culture tool comprises a membrane for cell culture which is arranged while covering the entire one end part of the first internal cylinder, and bent to the outside surface side of the first internal cylinder along a periphery of the one end part of the first internal cylinder. Further, the culture tool also comprises an external cylinder which is cylindrically formed and houses the first internal cylinder therein so as to match a height direction with that of the first internal cylinder, in which a first slit extending in the height direction is formed in a region overlapping at least the one end part of the first internal cylinder, and sandwiches the membrane for cell culture between an inner wall surface of the external cylinder and an outside surface of the first internal cylinder. |
