The present invention provides a method for manufacturing a polarizer sheet capable of suppressing the occurrence of dents in a polarizer and capable of manufacturing a polarizer sheet having an excellent appearance. This method for manufacturing a polarizer sheet is provided with: a step for forming a laminate by bonding a long surface protection film having a plurality of first through-holes to a long polarizer; a step for forming a plurality of non-polarizing parts by decoloring the portion of the polarizer exposed from the plurality of first through-holes; a step in which a laminate including a polarizer on which a plurality of non-polarizing parts are formed is wound into a roll; and a step in which a plurality of polarizer sheets each including a non-polarizing portion are cut from the polarizer after the winding. The surface protection film further has a second through-hole located between a first through-hole located at one end in the width direction among the plurality of first through-holes and one
