PURPOSE:To obtain a light transmission plate, useful as a filter for sunlight, capable of preventing dazzling, overheating in room and browning, having high intensity, by setting an adhesive layer prepared by blending a light filtering resin with a transparent adhesive resin between the insides of light transmission plates. CONSTITUTION:A light transmission plate obtained by setting an adhesive layer prepared by blending a light filtering resin with a transparent adhesive resin and, as necessary, adding colored pigment to the light filtering resin, between the insides of light transmission plates. When the adhesive layer is made of an adhesive resin obtained by semicuring a liquid resin, bonding operation can be carried out by casting the liquid resin between light transmission plates for laminating and the bonding operation is extremely readily effected, so that the operation is suitable for laminated light transmission plate having curved surface shape whose bonding operation is particularly difficult. Since the adhesive layer has light filtering ability, cracking at a wire net part by overheating will not occur when a light transmission plate having a net is used as the inside light transmission plate.
