Abstract
To improve the moldability and keeping cold performance of a vacuum heat insulating container. A constant temperature container includes a heat insulating container formed by disposing a core material between an outer cover material and an inner cover material and sealing the core material in a reduced-pressure state. The core material includes a first core material, the first core material being an organic substance made of open-cell foam, and a second core material having a lower thermal conductivity than the first core material at a vacuum degree of 100 Pa or less.
