PROBLEM TO BE SOLVED: To provide a laminate sheet production device and method capable of bonding continuously at high precision, and also to provide a laminate sheet roll. SOLUTION: Upon producing a laminate sheet by bonding a transparent sheet with another sheet, the laminate sheet is introduced in a detecting roll having a higher reflection coefficient than the transparent sheet, light is irradiated to the laminate sheet on the detecting roll, so as to receive scattering reflection lights from the laminate sheet and the detecting roll, which are then converted into an electric signal and the signal is calculated, and a position control order for a position control means for a material to be bonded is issued on the basis of this calculated result.
