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

摘要

A shape-retaining film which allows a flexible wiring board to retain its shape after the flexible wiring board is deformed by bending or the like, and a shape-retaining flexible wiring board including the shape-retaining film, is disclosed herein. A shape-retaining film includes a plastic-deformable metal layer and an adhesive layer which is formed on one surface side (lower side) of the metal layer 3 and is joined with a flexible wiring board. The shape-retaining film makes it possible to retain the shape of a deformed flexible wiring board. With this arrangement, the occurrence of a repellent force in the deformed flexible wiring board is prevented.
