<p>It is intended to provide a cell culture container whereby cells capable of efficiently presenting a shape or a function that is to be inherently expressed in vivo can be efficiently proliferated and/or differentiated. Namely, a cell culture container which is a cell culture container (10) having two-staged or higher concavo-convex pattern wherein the width of a concave (14) formed by the concavo-convex pattern is 1.0 to 40 times longer than the diameter of the cell to be cultured. In at least one stage in the two-staged or higher concavo-convex pattern, a concave (14) formed therein is communicated to at least one neighboring concave (14).</p>
