The present invention relates to a process for producing a polarizing film, comprising the steps of applying an adhesive of an active energy ray curable type to one side of a transparent film or one side or both sides of a polarizing film, and a lamination step of laminating a transparent film on one side or both sides of the polarizing film through an adhesive A joining step of joining the transparent film and the polarizing film by applying pressure to the laminate by sandwiching the laminate between a pair of joining rolls rotating in the conveying direction; A first active energy ray irradiation step of irradiating the laminate with an active energy ray to cure the adhesive, in this order, at least one of the pair of bonding rolls is a rubber Roll, and the rotation speed of the rotation roll is faster than the rotation speed of the rubber roll. |
