a sealing part configured to seal the first plate and the second plate;
a thermoelectric module provided in the vacuum space, and the thermoelectric module having a first temperature part and a second temperature part; and
a heat diffusion block having a third surface and a fourth surface,
wherein the heat diffusion block and the thermoelectric module are configured to perform heat transfer between the third surface of the heat diffusion block and the first temperature part of the thermoelectric module.

2. The insulated storage according to claim 1 , wherein the first temperature part of the thermoelectric module is to face the third surface of the heat diffusion block.

3. The insulated storage according to claim 2 , comprising a thermal interface module between the first temperature part of the thermoelectric module and the third surface of the heat diffusion block.

4. The insulated storage according to claim 1 , wherein the fourth surface of the heat diffusion block is to face the first plate, and the heat diffusion block and the first plate are configured to perform heat transfer between the first plate and the fourth surface of the heat diffusion block.

5. The insulated storage according to claim 4 , comprising a thermal interface module between the fourth surface of the heat diffusion block and the first plate.

6. The insulated storage according to claim 1 , wherein the second temperature part of the thermoelectric module is to face the second plate, and the thermoelectric module and the second plate are configured to perform heat transfer between the second temperature part of the thermoelectric module and the second plate.

7. The insulated storage according to claim 6 , comprising a thermal interface module between the second temperature part of the thermoelectric module and the second plate.

8. The insulated storage according to claim 1 , comprising:
a heat sink having a fifth surface and a sixth surface,
wherein heat transfer is to occur between the second temperature part of the thermoelectric module and the fifth surface of the heat sink.

9. An insulated storage comprising:
a first plate to have a first temperature;
a second plate to have a second temperature that is different from the first temperature;
a vacuum space provided between the first plate and the second plate to have a temperature between the first temperature and the second temperature;
a sealing part configured to seal the first plate and the second plate;
a thermoelectric module provided in the vacuum space, and the thermoelectric module to have a first temperature part and a second temperature part;
a heat diffusion block provided in the vacuum space between the thermoelectric module and the first plate; and
a first thermal interface module is provided between the first temperature part of the thermoelectric module and the heat diffusion block.

10. The insulated storage according to claim 9 , wherein a second thermal interface module is provided between the second temperature part of the thermoelectric module and the second plate.

11. The insulated storage according to claim 10 , wherein a third thermal interface module is provided between the heat diffusion block and the first plate.

12. An insulated storage comprising:

a wire to apply power to the thermoelectric module.

13. The insulated storage according to claim 12 , comprising:
a power source hole on the first plate or the second plate; and
a sealing terminal configured to block the power source hole.

14. The insulated storage according to claim 12 , wherein the wire comprises:
an inner conducting wire; and
a sheath to cover at least a portion of the inner conducting wire.

15. The insulated storage according to claim 14 , wherein the sheath includes protrusion sheaths spaced apart from each other to cover a portion of the inner conducting wire.

16. The insulated storage according to claim 12 , comprising:
a supporting structure configured to maintain the vacuum space;
wherein the supporting structure includes a wire guide opening to provide an opening for the wire to pass.

17. The insulated storage according to claim 16 , the supporting structure including at least two bars, wherein the wire guide opening is provided between one of the at least two bars and the other one of the at least two bars.

18. The insulated storage according to claim 16 , wherein the wire guide opening is integrated with a thermoelectric seating opening corresponding to a position of the thermoelectric module and an exhaust port seating opening corresponding to a position of an exhaust port.
