Abstract
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.
Claims10
A shape-retaining film which is to be joined with a flexible wiring board, comprising:
- a plastic-deformable metal layer;
- and
- an adhesive layer which is formed on one surface side of the metal layer and by which the plastic-deformable metal layer is to be joined with the flexible wiring board,
- wherein when the metal layer is joined with the flexible wiring board, the metal layer substantially maintains the shape of the flexible wiring board by virtue of plastic deformation of the metal layer in accordance with deformation of the flexible wiring board.
