Abstract

A cover glass of the present invention includes a sealing material layer on one surface, wherein the sealing material layer has a gap formed therein.

Claims

1. A cover glass, comprising a sealing material layer on one surface,

wherein the sealing material layer has a gap formed therein.

2. The cover glass according to claim 1, wherein a width of the gap of the sealing material layer is from 2% to 60% of an average width of the sealing material layer.

3. The cover glass according to claim 1, wherein the gap is formed along a center line of the sealing material layer.

4. The cover glass according to claim 1, wherein the sealing material layer is formed in a frame shape along a peripheral end edge of the cover glass.

5. The cover glass according to claim 1, wherein the sealing material layer has an average thickness of less than 8.0 μ

m.

10. The cover glass according to claim 2, wherein the gap is formed along a center line of the sealing material layer.

6. A hermetic package, comprising a package base and a cover glass,

wherein the hermetic package further comprises a sealing material layer arranged between the package base and the cover glass, and

wherein the sealing material layer has a gap formed therein.

7. The hermetic package according to claim 6, wherein a width of the gap of the sealing material layer is from 2% to 60% of an average width of the sealing material layer.

8. The hermetic package according to claim 6,

wherein the package base comprises a base part and a frame part formed on the base part,

wherein the package base has an internal device housed within the frame part, and

wherein the sealing material layer is arranged between a top of the frame part of the package base and the cover glass.

9. The hermetic package according to claim 6, wherein the package base comprises any one of glass, glass ceramic, aluminum nitride, and aluminum oxide, or a composite material thereof.
