PROBLEM TO BE SOLVED: To provide a metal laminated body having a polyimide film being excellent in easy slipping property, which reduces the adhesion between films at a hinge section when multi-layer boards are laminated by heat-pressing, and can solve a "sounding" trouble by the abrasion between the films. SOLUTION: For this easily slippable metal laminated body, a polyimide film having a large number of stripe-form unevennesses of which the height difference is in a range of 0.05 to 10μm on the surface, and for which the maximum height Ry for the height difference of the stripe-form unevenness is in a range of 4 to 10μm is used as the base material. Then, the easily slippable metal laminated body is constituted by laminating a metal on the rear surface of the base material. COPYRIGHT: (C)2008,JPO&INPIT |
