Shape-retaining film and shape-retaining flexible wiring board provided with the shape-retaining film

摘要

An object of the present invention is to provide a shape-holding film that can be held in a deformed state by bending the flexible wiring board and the like, and a shape-holding flexible wiring board including the shape-holding film. The shape-retaining film 1 includes a plastically deformable metal layer 3 and an adhesive layer 4 that is formed on one side (lower side) of the metal layer 3 and bonded to the flexible wiring board 8. . The shape holding film 1 can hold the shape of the flexible wiring board 8 in a deformed state. Thereby, repulsive force can be prevented from being generated in the deformed flexible wiring board 8.
