Cell culture device and cell culture method

A cell culture device comprising:

• a band-shaped flexible member, the band-shaped member being configured to be circumferentially windable, wherein
• in a state in which the band-shaped member is circumferentially wound, the band-shaped member has an inner circumferential surface and an outer circumferential surface, at least one of which is provided with a plurality of wells each having a concave shape, the plurality of wells adjusted for cells to be cultured therein,
• at least some of the plurality of wells are connected to each other by a culture solution conduit adjusted for a culture solution to flow therethrough, and
• the plurality of wells and the culture solution conduit are covered by directly contacting the outer circumferential surface of the band-shaped member wound on an inner circumferential side of the plurality of wells and the culture solution conduit, or by directly contacting the inner circumferential surface of the band-shaped member wound on an outer circumferential side of the plurality of wells and the culture solution conduit,
• wherein the culture solution conduit includes a connection conduit that connect at least some of the plurality of wells,
• wherein the connection conduit connects the lower wells from the upper portions of each of the plurality of wells and is inclined upward, and
• wherein the plurality of wells are provided in a staggered manner on a circumferential surface of the band-shaped member.
