SPHERE CULTIVATING MEMBER, CULTIVATION CONTAINER, METHOD FOR PROCESSING PERFORATED MEMBER, AND CLEANING CONTAINER

摘要

It is possible to efficiently replace a medium, clean spheres, and arrange spheres at regular intervals in the formation of spheres. A member is capable of capturing spheres, the member having a first surface and a second surface on an opposite side of the first surface, and having a plurality of recesses; the recess having an opening formed in the first surface, and one microhole being formed for each opening in the second surface; a circle or inscribed circle of the opening having a diameter a of 50 µm or more and 1 mm or less, a circle or inscribed circle of the microhole having a diameter b of 1 µm or more and less than 200 µm, and a and b satisfying a>b.
