A method for producing a polarizing film with good transportability is provided. A step (1) of subjecting a polarizer having a moisture content of 11% by weight or less to an activation treatment to increase the surface roughness (Ra) to 0.6 nm or more, and guiding the surface of the activated polarizer. The step (2) of conveying while contacting the roll, the step (3) of applying an adhesive to the polarizer and / or the transparent protective film, and the step of bonding the polarizer and the transparent protective film through the adhesive. (4), A manufacturing method of a polarizing film characterized by things. [Selection] Figure 1 |
