る。In FIG. 3A, reference numeral 1 denotes a metal plate made of stainless steel having a thickness of, for example, 0.1 mm to be drawn. First, as shown in FIG. 3A, one surface of the metal plate 1 has a thickness of, for example, 25 μm. An adhesive sheet having an ethylene-vinyl acetate copolymer adhesive 3 is adhered on one surface of a release film 2 of polyethylene terephthalate (S10 manufactured by Toray Industries, Inc.) and a protective film is formed on the other surface of the metal plate 1. A flexible film with an adhesive (# 623E manufactured by Sekisui Chemical Co., Ltd., thickness 75 μm) 4 is laminated.

ある。In this case, the mat depth is 1 μm to 10 μm.
The range of μm (Rmax) is good. When the mat depth is set to 10 μm or more, there is a disadvantage that the peeling of the adhesive 3 described later becomes heavy. When the thickness of the film 2a is as thin as about 25 μm, the mechanical strength such as tensile strength and elongation is reduced.
4.0 μm is preferred. As this matted polyethylene terephthalate, Teijin PS-25 can be used. The mat depth of the polyethylene terephthalate film 2a having a thickness of 25 μm used in this example was measured using a surface roughness meter (kosakalabory Ltd Model SP
-11, AS-3H, RA-60A), Ra = 0.27 μm and Rmax = 3.31 μm. Here, Ra is the center line average roughness, and Rmax is the maximum height.
