Abstract: In a polarizing lens L which is obtained by a process in which a polarizing plate H formed by bonding protective films 2 and 3 to the both sides of a polarizing thin film 1 of polyvinyl alcohol, a thermoplastic resin film 10 is bonded to one side of the polarizing plate H with an adhesive or a sticking agent, the thermoplastic resin film 10 is subjected to curved molding such that this thermoplastic resin film 10 is positioned on the concave surface side, and a thermoplastic resin molded layer 11 formed of the same resin as that for the thermoplastic resin film 10 is laminated on the concave surface of this polarizing plate H, the protective films 2 and 3 are bonded to both sides of the polarizing thin film 1 with an adhesive, and a mixture of an epoxy resin and an acid anhydride is used as the adhesive.
