Title: LAMINATE, METHOD FOR PRODUCING SAME, AND FLEXIBLE PRINTED CIRCUIT BOARD
Abstract:
The present invention provides: a laminate having a resin layer that contains a crystalline alicyclic-structure-containing resin, the resin layer having an average linear expansion coefficient of 10-50 ppm/°C at 60-100°C, and a metal layer in direct contact with the resin layer, wherein the laminate is characterized in that the ten-point average roughness (Rz) of the interface between the resin layer and the metal layer is 2.0 μm or less; a method for producing the laminate; and a flexible printed circuit board in which the laminate is used. According to the present invention, there are provided: a laminate that has a metal layer and a resin layer that contains a crystalline alicyclic-structure-containing resin, the laminate being suitably used as a substrate material; a method for producing the laminate; and a flexible printed circuit board in which the laminate is used.
