PROBLEM TO BE SOLVED: To provide a flexible laminate in which an inexpensive polyimide resin layer least prone to heat deformation and a metal layer are laminated and its manufacturing method. SOLUTION: The flexible laminate comprises polyimide layers and metal layers and is obtained by laminating (b) layers of a polyimide resin having a glass transition temperature of 200-300°C on both of the outer sides of (a) a layer of a polyimide resin having a glass transition temperature of≥350°C, laminating (c) layers of a polyimide resin having a glass transition temperature of≥350°C on both sides of the laminate composed of (a) and (b), laminating (d) a layer of a polyimide resin having a glass transition temperature of≥300°C on both sides of the laminate composed of (a), (b) and (c) and laminating (e) metal layers on both sides of the laminate composed of (a), (b), (c) and (d). The manufacturing process for the laminate is also disclosed. COPYRIGHT: (C)2007,JPO&INPIT |
