This manufacturing method for a polarizing plate attaches transparent films (2, 3) to one or both sides of a polarizing film (1). The manufacturing method for a polarizing film is characterized by comprising: an adhesive application step for applying an active energy beam curable adhesive to one surface of the transparent films (2, 3) or one surface or both surfaces of the polarizing film (1); an attachment step for attaching the transparent films (2, 3) to the polarizing film (1) in a state where a laminate (4) in which the transparent films (2, 3) are laminated on one surface or both surfaces of the polarizing film (1) via the adhesive are sandwiched between a pair of attachment rolls (51, 52) that rotate in a feed direction where either or both of the attachment rolls is pressed in the direction of the other attachment roll; and an active energy beam irradiation step that irradiates the laminate (4) with an active energy beam and cures the adhesive. The manufacturing method for a polarizing film is further characterized by one of the pair of attachment rolls (51, 52) being a crown roll (52) having a tapered peripheral shape that becomes smaller in diameter from the middle part to the edge parts. |
