<p>The present invention provides a method of manufacturing polarizing film, which has a first step of sequentially stretching a plurality of polyvinyl alcohol-based resin film; and a second step of connecting the foregone terminal part of the first polyvinyl alcohol-based resin film and the following front part of the second polyvinyl alcohol-based resin film by welding. In the second step, the terminal part is coincident with the front part, and the initial elasticity modulus of the engaging part is more than 65% and less than 100% with respect to the initial modulus of non-engaging parts.</p> |
