Title: LAMINATED GLASS
Abstract:
Provided is a laminated glass such that the occurrence of a protruding portion in an intermediate film at an end portion of the laminated glass is suppressed and the appearance of the laminated glass can be satisfactorily maintained. The laminated glass according to the present invention comprises a first laminated glass member, a second laminated glass member, and an intermediate film including a thermoplastic resin. When the laminated glass is subjected to a light illumination test in which: "the laminated glass is subjected to four cycles of a process in which the laminated glass is irradiated with xenon light for 144 hours at a black panel temperature of 83°C and a humidity of 50% RH, and then the laminated glass is immersed for 24 hours in pure water at 80°C", a ratio of weight average molecular weight of the thermoplastic resin at a position at a distance of 2 mm from the end portion of the laminated glass to the inside to the weight average molecular weight of the thermoplastic resin at a position at a distance of 70 mm from the end portion of the laminated glass to the inside exceeds 0.5.
