Laminated film defect inspection method and laminated film defect inspection device

A device for inspecting a defect of a laminated film that inspects a defect of a wounded up laminated film, the device comprising:

• a laminated film supply device for supplying a laminated film in which a protective film on a front surface of a film body and a separator on an adhesive surface on a back side of the film body are laminated together;
• a separator separation device for separating the separator from the laminated film while introducing the laminated film fed out from the laminated film supply device to a predetermined path;
• an inspection device for making a separation surface of a separator face downward at least at the separation point of the separator, and inspecting presence of the defect while maintaining this state and transporting;
• a storage device for storing information of the inspection result;
• a separator supply device for feeding out a separator to a back surface of the film body;
• a separator laminating device for laminating the separator fed out from the separator supply device to the separation surface with the separation surface of the separator of the inspected film body facing downward;
• and
• a laminated film collecting device for winding up the inspected laminated film in which the separator is laminated to the back surface of the film body.
