Abstract
A living cell cryopreservation tool has a body part formed of a cold-resistant material and a living cell holding part formed of the cold-resistant material. The living cell holding part has a long and narrow living cell attaching and holding portion. The living cell attaching and holding portion has a plurality of living cell accommodation concave portions formed in a longitudinal direction thereof and a plurality of excess cryopreservation liquid discharge passages communicating with the living cell accommodation concave portions.
