Abstract: Laminated glass includes a first glass sheet; a second glass sheet; and an interlayer positioned between the first and second glass sheets, to bond the first and second glass sheets together. The laminated glass has a first area used by a head-up display, and a second area adjacent to the first area and not used by the head-up display. One or both of the first and second glass sheets are wedge-shaped. At one or more points in at least a part of an area of the second area, a wedge angle δg being a sum of respective wedge angles of the first and second glass sheets satisfies Formula (1): δ g = t R sin φcosφ n 2 - sin 2 φ - η cos φ 2 n 2 - sin 2 φ - δ c - δ i ( 1 ) where t, R, n, φ, η, δc, and δi are as specified in claim 1.
