Abstract
A cell culture container has a bottom face and a surface having a dent-formed region having a plurality of dents with an average depth of 200 μm or more, the formula θ1<90−θ2+sin{sin(θ2)×1.38/n} is satisfied wherein θ1 (deg) is the angle formed by a first tangent line which passes a connecting point of a first curved line corresponding to a first dent and a second curved line corresponding to a second dent and which is in contact with the first curved line, and a base line which passes the connecting point and which is in parallel with the bottom face, and n is the refractive index of the substrate, and the formula θ2<90−θ1+sin{sin(θ1)×1.38/n} is satisfied wherein θ2 (deg) is the angle formed by a second tangent line which passes the connecting point and which is in contact with the second curved line, and the base line.
