A polarizing plate manufacturing method and a polarizing plate manufacturing apparatus capable of uniformly pressing a laminate (polarizing film and transparent film) constituting a polarizing plate are provided. A method of manufacturing a polarizing plate in which a transparent film is bonded to one or both sides of a polarizing film, wherein an adhesive coating step of applying an active energy ray-curable adhesive, and the transparent film is polarized In a state in which a laminate formed by laminating an adhesive on one side or both sides of a film is sandwiched between a pair of laminating rolls rotating in the transport direction, at least one laminating roll is placed on the other laminating roll. By pressing in the direction, a bonding process for bonding the transparent film and the polarizing film, and an active energy ray irradiation process for irradiating the laminate with active energy rays to cure the adhesive, a pair of bonding One of the rolls 51 and 52 is a crown roll 52 having a tapered outer peripheral shape whose diameter decreases from the center to the end.
