摘要：
A frozen biological cell pellet preparation device 1 comprises: a device body 2 comprising a funnel part 20 that decreases in diameter toward a sampling container connection opening 24, and legs 31a, 31b, 31c; and a plate-shaped member 4 housed within the upper part of the funnel part 20. The funnel part 20 comprises a plurality of side holes 26, and the plate-shaped member 4 comprises a plurality of through-holes 42. The device body 2 and plate-shaped member 4 are submerged in liquid nitrogen, in which state a biological-cell-containing liquid is introduced dropwise from above the plate-shaped member 4, thereby forming frozen biological cell pellets in the through-holes 42 of the plate-shaped member 4. The frozen biological cell pellets descend through the funnel part and are guided into the sampling container connection opening 24.
