1. A laminated glass on which an information acquisition device for acquiring information from outside of a vehicle by emitting and/or receiving light is arrangeable, the laminated glass comprising:
an outer glass plate;
an inner glass plate;
an interlayer film arranged between the outer glass plate and the inner glass plate; and
a mask layer laminated on at least one of a surface on a vehicle interior side of the outer glass plate or a surface on a vehicle interior side of the inner glass plate,
wherein the interlayer film includes:
a colored shade region;
a transparent non-shade region; and
a transparent sheet member fitted into at least one through hole formed over the shade region and the non-shade region,
the mask layer includes at least one opening that is formed on an inner side relative to an edge portion of the sheet member at a position corresponding to the sheet member,
the light of the information acquisition device passes through the opening,
when a thickness between an outer surface of the outer glass plate and an inner surface of the inner glass plate at a central point of the sheet member is defined as H1, a thickness between the outer surface of the outer glass plate and the inner surface of the inner glass plate at a point that is 400 mm away from the edge portion of the sheet member on a virtual line extending in a horizontal direction through the central point is defined as H2, and
any point A on an inner edge of the opening, a point B that is the shortest distance from the point A on an outer edge of the sheet member, and a point C at which a virtual line extending from the point A through the point B and an outer edge of the mask layer intersect each other,
a distance between the point A and the point B is defined as S1, and a distance between the point B and the point C is defined as S2,
when H1 is greater than H2, S1 is smaller than S2 at a location where S1+S2 is minimized,
when H1 is less than H2, S1 is greater than S2 at a location where S1+S2 is minimized, and
|H1-H2|≥120 μm.
