Abstract
Provided is a culture chamber that includes a plurality of recesses each formed of a bottom portion and an opening portion. The bottom portion has a hemispherical shape or a truncated cone shape. The opening portion is defined by a wall that surrounds an area from a boundary between the opening portion and the bottom portion to an end of each of the recesses, the wall having a taper angle in a range from 1 to 20 degrees. An equivalent diameter of the boundary is from 50 μm to 2 mm and a depth from a bottom of the bottom portion to the end of each of the recesses is from 0.6 or more times to 3 or less times the equivalent diameter, and the wall defining the opening portion forms a surface continuous to the bottom portion. An inclination of the continuous surface changes at the boundary.
