A temperature-management system provided with the following: a thermally insulated outer container (2)； a thermally conductive inner container (3) that contains a drug under test or other object such that same can be placed into and removed from the outer container； one or more first upper and lower heat-storage materials (4a, 4b)； and one or more second upper and lower heat-storage materials (5a, 5b). The first and second lower heat-storage materials (4a, 5a) are placed in surface contact with each other, the second lower heat-storage materials (5a) are arranged inside the outer container towards the bottom thereof, the inner container is placed on top of the first lower heat-storage material (4a) inside the outer container, the first and second upper heat-storage materials (4b, 5b) are placed in surface contact with each other, and the first upper heat-storage material (4b) is disposed so as to contact the top of the inner container. The first upper and lower heat-storage materials (4a, 4b) are thus cooled by the second upper and lower heat-storage materials (5a, 5b) and the resulting heat of fusion from the first upper and lower heat-storage materials is conducted to the interior of the inner container, thereby maintaining the interior of the inner container at a prescribed temperature and consequently maintaining the contents thereof at a prescribed temperature.
