Zusammenfassung: | A cell sheet-forming member provided with a surface for forming a cell sheet, wherein the surface comprises a plurality of flat parts and a plurality of concavo-convex parts. Each flat part has a shape extending along a first direction and the plurality of the flat parts are aligned along a second direction intersecting with the first direction over the entire surface. Either of convex parts or concave parts have a stepped structure and individual concave and convex parts include a plurality of the stepped structures which fill gaps between flat parts adjacent to each other, wherein the pitch of said stepped structures is from 100 nm to 10 µm inclusive. |
