Abstract
A cell cryopreservation tool has a cell holding member having a body part and a cell holding part and a tubular accommodation member, closed at one end thereof, which is capable of accommodating the cell holding member. The cell holding part of the cell holding member has a long and narrow cell attaching and holding portion. The cell attaching and holding portion has a heat conductor extended in a longitudinal direction thereof. When the cell holding member is accommodated in the tubular accommodation member, the heat conductor is capable of contacting an inner surface of the tubular accommodation member.
