To provide a cold storage means that reliably cools an object to be cooled and stays cool for a long time, a corpse storage means for which the object to be cooled is a corpse, and a cooling device set. The cooling device set (1) comprises a cold storage means (10) and a cooling device (90). The cooling device and the cold storage means can be separated so that the secondary refrigerant does not leak out when the cold storage means has been cooled. In the cold storage means (10), a refrigerant circulation duct (14) is formed along a first plane-shaped body so that the secondary refrigerant, which becomes liquid in a desired cooling temperature range, can be circulated with a desired spacing, and a shape-maintaining means (12) is provided so that the refrigerant circulation duct is not crushed. Preferably, the primary refrigerant is a natural refrigerant. Ideally, the shape-maintaining means (12) is a liquid and is a tertiary refrigerant.本發明為提供一種確實使冷卻對象冷卻，並且冷卻時間較長的冷卻保存手段、待冷卻對象為遺體的遺體保存手段以及冷卻裝置組。本發明包含冷卻保存手段(10)以及冷卻裝置(90)的冷卻裝置組(1)。在冷卻保存手段已冷卻的狀態下，二次冷媒不會漏出而呈能夠分離的冷卻裝置與冷卻保存手段。在冷卻保存手段(10)中，冷媒循環管路(14)係使在所需的冷卻溫度範圍下呈液體狀態的二次冷媒能夠以所需的間隔循環，且沿著第一平面狀體形成。此外，冷媒循環管路具有呈不會塌陷狀態的形狀保持手段(12)。一次冷媒較佳為自然冷媒，且形狀保持手段(12) 較佳為液狀體並且為三次冷媒。
