Abstract
The present multi-layered structure includes: a resin layer; a glass layer stacked via an adhesive layer on the resin layer; and a fusion layer that is formed in an outer peripheral portion of the glass layer on the glass layer side that faces the adhesive layer. A thickness of the glass layer is 10 μm or more and 300 μm or less. A thickness of the fusion layer is less than 3 μm.
Claims9
A multi-layered structure, comprising:
- a resin layer;
- a glass layer stacked via an adhesive layer on the resin layer;
- and
- a fusion layer that is defined by a heat-damaged region of an outer peripheral portion of the glass layer, the heat-damaged region having a residual stress and formed on a glass layer side that faces the adhesive layer,
- wherein the outer peripheral portion of the glass layer projects from a side face of the resin layer,
- wherein an amount of projection of the outer peripheral portion of the glass layer from the side face of the resin layer is less than 15 μm,
- wherein a thickness of the glass layer is 10 μm or more and 300 μm or less,
- a thickness of the fusion layer is less than 3 μm, and
- wherein the fusion layer is continuously exposed on a bottom face and a side face of the glass layer.
