Cell culture chip

Abstract

A cell culture chip from which a liquid retained in an opening is able to be sucked by a simple operation procedure while a liquid in a channel remains is provided. A cell culture chip according to the present invention includes a bottom portion; a base portion formed on an upper surface of the bottom portion; a first well provided by opening the base portion in a first direction extending from a portion of a main surface of the base portion toward the bottom portion and having a shape such that a capillary force thereof is smaller than that of the chamber; a second well provided by opening the base portion in the first direction at a position separated from the first well in a second direction parallel to the main surface; and a tubular chamber that is defined by a region sandwiched between the bottom portion and the base portion and that provides communication between the first and second wells in the second direction. The first well has a shape with which a capillary force of the first well is smaller than a capillary force of the chamber.
