Abstract

PURPOSE:To improve a dimensional stability without deteriorating a flexibility by a method wherein a substrate containing at least a conductor and a insulating material is provided, where the linear expansion coefficient and the extensibility of the insulating material are specified. CONSTITUTION:A flexible printed substrate is provided, where an insulating layer adheres to a conductor through intermediary of an adhesive agent, a patterning and a etching are performed thereon, and a adhesive agent usedin the manufacture of a usual flexible printed substrate can be used. An conductor consists of such a metal as is represented by copper, iron, or aluminum, or a foil of them, or a material other than them. If the insulating material used as a important material is less than 2.0X10<-5>/ deg.C in linear expansion coefficient and more than 30% in extensibility when a tensile break takes place, it is usable, where a synthetic resin, especially polyimide is desirable. In polyimide, an aromatic polyimide copolymer represented by constitutional formulas A and B is desirable.
