The present invention is a laminated glass having an average transmittance TA of 15% or less at a wavelength of 900 to 1300 nm through thereof from one face. According to the present invention, there can be provided a laminated glass by which monitoring can be properly carried out using infrared radiation even when an infrared monitoring system is introduced in various vehicles.

The laminated glass of the present invention is a laminated glass comprising an infrared reflective layer, wherein an average reflectance R(A) at a wavelength of 900 to 1300 nm at an incident angle of 60° on one face is 20% or less. According to the present invention, even when an infrared reflective layer is provided in the laminated glass, infrared radiation incident on one face is prevented from being reflected on the infrared reflective layer, and monitoring accuracy in the infrared monitoring system is improved.

The laminated glass of the present invention has a T/R rate (A) of larger than 1, the T/R rate (A) being calculated from the following formula (1):

T/R rate (A)=log 10(TA/100)/log 10(RA/100)  (1)

wherein an average transmittance at a wavelength of 900 to 1300 nm through one face is represented by TA, and a maximum reflectance at a wavelength of 900 to 1300 nm at an incident angle of 60° on the other face is represented by RA.
