To provide laminated glass using an intermediate film having a wedge angle profile that is capable of reducing a double image on a HUD resulting from the influence of the curvature in the longitudinal direction of a window as well as the curvature in the horizontal direction of the window, with a configuration allowing easy manufacturing. Laminated glass for a vehicle front window including: a curved first glass plate having a trapezoidal or rectangular shape; a second glass plate having the same shape as the first glass plate; and an intermediate film disposed between the first and second glass plates, wherein an imaging section of an image projected from an imaging device incorporated in a dash board on a driver's seat side is included in an indoor side surface of the laminated glass in a state in which the laminated glass is incorporated in a vehicle body, the intermediate film is provided with a wedge angle profile in a longitudinal direction and a horizontal direction of the laminated glass, and a thickness based on the wedge angle profile of the intermediate film based on the wedge angle profile continuously decreases from an upper side to a lower side and continuously decreases in a direction from a driver's seat side to a passenger seat side.
