Abstract
Provided is laminated glass capable of preventing generation of a void in the interlayer film in an end part of laminated glass, and keeping the appearance of laminated glass excellent. Laminated glass according to the present invention is laminate glass including a first lamination glass member, a second lamination glass member, and an interlayer film containing a thermoplastic resin, and no void is generated in the interlayer film irradiated with light in an end part of the laminated glass after a first light irradiation test: 'conducting 4 cycles each cycle including the process of irradiating the laminated glass with xenon light 180 W/mat a black panel temperature of 83° C. and a humidity of 50% RH for 144 hours, and dipping the laminated glass in pure water at 80° C. for 24 hours', or a void is generated within a length of 1 mm or less inwardly from an end part of the interlayer film irradiated with light in the end part of the laminated glass after the first light irradiation test.
