A cell culture transferring instrument includes a cylindrical body held by an operator not shown in the drawing, a plunger inserted through the interior of the cylindrical body, a plurality of support members connected to a distal end of the plunger, and an adsorbent capable of adsorbing a sheet-shaped cell culture held by the support members. The support members in contact with the distal end of the cylindrical body are elastically deformed by displacing the plunger toward the proximal end side with respect to the cylindrical body in a state in which the sheet-shaped cell culture is adsorbed to the adsorbent, whereby the adsorbent and the sheet-shaped cell culture are deformed and housed in a housing hole in the cylindrical body.
