To provide a refrigeration/heat-insulation apparatus capable of satisfactorily cooling the inside of a chamber while suppressing an increase of energy consumption and enlargement of the apparatus large.

There are provided a casing 10 having a cutout portion 10a, an inner wall of which is formed with a heat pipe panel 14 and which is cut out from outside so as to expose the heat pipe panel 14, a heat absorption surface 21b for absorbing heat through power supply, and a heat dissipation surface 21a for producing heat through power supply, and a cover for sealing the casing 10. In this case, the heat absorption surface 21b is connected with the heat panel 14 from the cutout portion 10a in the casing 10.
