The present invention aims to provide an automotive laminated glass in light of warpage of chemically strengthened glass, and a method of producing the automotive laminated glass. The present invention provides an automotive laminated glass, including: a thermoplastic interlayer film (3); a curved first glass sheet (21); and a curved second glass sheet (22), the thermoplastic interlayer film being disposed between the first and second glass sheets, wherein the first glass sheet is a 0.7- to 3-mm thick non-chemically strengthened glass sheet including a convex-side first main surface (211) and a concave-side second main surface (212) facing the thermoplastic interlayer film, the second glass sheet is an ion-exchanged, 0.3- to 1.5-mm thick chemically strengthened glass sheet including a convex-side third main surface (223) facing the thermoplastic interlayer film and a concave-side fourth main surface (224), the second glass sheet being thinner than the first glass sheet, the convex-side third main surface has a compressive stress layer thicker than that on the concave-side fourth main surface, and the second glass sheet is adjusted to fit the curvature of the first glass sheet.
