Abstract

A plurality of heat dissipation substrates stacked on each other, intermediate sheets disposed under a lowermost heat dissipation substrate, on an uppermost heat dissipation substrate, and between heat dissipation substrates adjacent to each other, a drying agent disposed over or under the plurality of heat dissipation substrates, and a bag that seals the plurality of heat dissipation substrates, the plurality of intermediate sheets, and the drying agent.

First claim

The invention claimed is:

1. A package comprising:
a plurality of heat dissipation substrates stacked on each other;
intermediate sheets disposed under a lowermost heat dissipation substrate, on an uppermost heat dissipation substrate, and between heat dissipation substrates adjacent to each other;
a sheet drying agent disposed over or under the plurality of heat dissipation substrates; and
a bag that seals the plurality of heat dissipation substrates, the plurality of intermediate sheets, and the sheet drying agent in a stacked state.

2. The package according to claim 1 ,
wherein a water vapor permeability of the bag, which is measured in accordance with JIS Z 0222: 1959, is equal to or more than 0.1 g/m 2 ·day and equal to or less than 15.0 g/m 2 ·day.

3. The package according to claim 1 , wherein an oxygen permeability of the bag, which is measured in accordance with JIS K 7126-2: 2006, is equal to or more than 0.1 cm 3 /(m 2 ·24 h·atm) and equal to or less than 50.0 cm 3 /(m 2 ·24 h·atm).

4. The package according to claim 1 ,
wherein the heat dissipation substrate is a plate-like substrate made of a metal-silicon carbide composite in which a silicon carbide porous material is impregnated with metal containing any one of aluminum and magnesium.

5. The package according to claim 1 ,
wherein the bag is made of an aluminum laminated film.

6. The package according to claim 1 ,
wherein the intermediate sheet is a paper-based base material.

7. The package according to claim 1 ,
wherein the intermediate sheet disposed on the uppermost heat dissipation substrate covers side surfaces of at least one heat dissipation substrate.

8. The package according to claim 1 ,
wherein the number of the heat dissipation substrates laminated is equal to or more than two and equal to or less than six.

9. The package according to claim 1 ,
wherein an end portion of the bag is heat-sealed.

10. The package according to claim 1 ,
wherein the bag seals the plurality of heat dissipation substrates, the plurality of intermediate sheets, and the sheet drying agent in a vacuum state.

11. A packing box comprising:
a plurality of the packages according to claim 1 ; and
a cushioning material provided in at least a part of a periphery of the packages in the packing box.
