Cell culture container and cell culture system

A cell culture container comprising:

• a container body;
• a second electrode;
• a cell culture insert having a tubular portion and an oxygen-permeable membrane;
• and
• a lid member, wherein
• the container body is provided with an opening that communicates with an interior of the container body,
• the second electrode is embedded in the container body so as to be electrically connected to a second culture medium stored in the interior of the container body,
• the tubular portion includes an upper end and a lower end, and is inserted in the opening such that the lower end is located inside the container body,
• the lower end of the tubular portion is closed by the membrane,
• the upper end of the tubular portion is closed by the lid member,
• the lid member includes a lower surface that faces toward an interior of the tubular portion,
• the lid member is provided with a culture medium inlet port through which a first culture medium is supplied into the tubular portion, an electrode insertion port into which a first electrode is inserted so as to electrically connect the first culture medium, and a culture medium outlet port,
• each of the electrode insertion port, the culture medium inlet port and the culture medium outlet port communicates with the interior of the tubular portion at the lower surface, and
• a distance between the membrane and the lower surface monotonically increases from a lower surface side end of the electrode insertion port toward a lower surface side end of the culture medium outlet port.
