Abstract

A multi-layer structure includes a glass layer having a thickness of greater than or equal to 10 μm and less than or equal to 200 μm; and a resin layer. A number of unit lamination structures in a thickness direction of the multi-layer structure is greater than or equal to 5 and less than or equal to 20,000, the unit lamination structure being a lamination structure composed of the glass layer and the resin layer.

Claims (18)

1. A multi-layer structure comprising:

unit lamination structures, wherein each unit lamination structure of the unit lamination structures is a lamination structure composed of:

a glass layer having a thickness of greater than or equal to 10 μm and less than or equal to 200 μm;

a resin layer, the resin layer includes a flexible resin film, and

a bonding layer or an adhesive layer provided between the resin film and the glass layer; and

wherein a total number of unit lamination structure of the unit lamination structures in a thickness direction of the multi-layer structure is greater than or equal to 5 structures and less than or equal to 20,000 structures,

and

wherein a thickness of the resin layer of each unit lamination structure is in a range from more than 50 μm and up to 1 mm.

2. The multi-layer structure according to claim 1 ,

wherein the multi-layer structure has a cylindrical shape.

3. The multi-layer structure according to claim 1 ,

wherein one resin layer of one of the unit lamination structure of the unit lamination structures is composed of ethylene vinyl acetate.

4. The multi-layer structure according to claim 1 ,

wherein one resin layer of one of the unit lamination structure of the unit lamination structures is composed of polyvinyl butyral.

5. The multi-layer structure according to claim 1 ,

wherein the total number of unit lamination structure of the unit lamination structures in the thickness direction of the multi-layer structure is greater than or equal to 10 structures and less than or equal to 20,000 structures.

6. The multi-layer structure according to claim 1 ,

wherein the total number of unit lamination structure of the unit lamination structures in the thickness direction of the multi-layer structure is greater than or equal to 20 structures and less than or equal to 20,000 structures.
