The present invention having a thickness of 50 ㎛ or less polyvinyl alcohol-based resin plastic film bonding process to bond the resin film formed on one surface of the substrate film to obtain a laminated film in and, as the drawing process to dismiss the laminated film stretching, the uniaxially stretched the resin film of the laminated film made of the dyeing, including the dyeing step of forming the polarizer layer in this order with a dichroic dye, a base film and a light-shielding section having a polarizer layer formed on one surface of a base film laminated film there is provided a method. According to the present invention, without causing a problem in that the end portion folded into the base film, there can be provided a method for producing a light-shielding laminated film piece having a thin layer of the polarizer.
