LAMINATED GLASS
First Claim
1. A laminated glass comprising:
- a first glass plate; and
a second glass plate bonded to the first glass plate with an interlayer disposed therebetween, the laminated glass comprising;
a first main surface of the first glass plate arranged on a side opposite to the interlayer;
a second main surface of the first glass plate being in contact with the interlayer;
a third main surface of the second glass plate being in contact with the interlayer;
a fourth main surface of the second glass plate arranged on a side opposite to the interlayer;
a first region located on the first main surface; and
a second region which is located on the fourth main surface and at least a part of which overlaps the first region in a plane view,wherein at least one of the first region and the second region has an arithmetical mean height of roughness profile Ra of 0.5 μ
m or less, a mean length of roughness-profile elements RSm of 40 μ
m or less, an arithmetical mean height of waviness profile Wa of 10 μ
m or less, and a mean length of waviness-profile elements WSm of 60 mm or less, as provided for in JIS B 0601;

Abstract
A laminated glass includes a first glass plate, a second glass plate, and an interlayer interposed between the first glass plate and the second glass plate. The first glass plate includes a first main surface arranged on a side opposite to the interlayer and a second main surface in contact with the interlayer, while the second glass plate includes a third main surface in contact with the interlayer and a fourth main surface arranged on a side opposite to the interlayer. The laminated glass includes a first region located on the first main surface and a second region which is located on the fourth main surface and at least a part of which overlaps the first region in a plane view. The first region and the second region have a given glass-surface smoothness.
