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.

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)
