Laminated glass

Abstract

A laminated glass according to the present invention includes an outer glass sheet, an inner glass sheet that is arranged opposite to the outer glass sheet and has a smaller thickness than that of the outer glass sheet, and an interlayer sandwiched between the outer glass sheet and the inner glass sheet. A transmittance with respect to light having a wavelength of 850 to 950 nm is 30 to 80%. The outer glass sheet has a thickness of 1.8 to 2.3 mm. The inner glass sheet has a thickness of 0.6 to 2.0 mm. The interlayer includes a plurality of layers including at least a core layer. The core layer has a Young's modulus of 1 to 20 MPa at a frequency of 100 Hz and a temperature of 20° C., the Young's modulus being lower than the Young's modulus of the other layer.
