SHAPE-RETAINING FILM AND SHAPE-RETAINING-TYPE FLEXIBLE CIRCUIT BOARD PROVIDED WITH SAME SHAPE-RETAINING FILM

摘要

An object of the present invention is to provide a shape-retaining film that can be maintained in a deformed state by bending a flexible wiring board, and a shape-retaining flexible wiring board provided with the shape-retaining film. The shape maintaining film 1 is provided with the metal layer 3 which can be plastically deformed, and the adhesive bond layer 4 formed in the one surface side (lower side) of the metal layer 3, and adhere | attached to the flexible wiring board 8. The shape maintaining film 1 can shape-retain the flexible wiring board 8 in a deformed state. This can prevent the repulsion from occurring in the deformed flexible wiring board 8.
