PROBLEM TO BE SOLVED: To provide a polyimide composite having excellent adhesion, water resistance, or the like, without losing the heat resistance, electric insulation, mechanical characteristics, or the like of the polyimide resin itself, a varnish for forming the polyimide composite, and a film from the polyimide composite, and also both a metal-clad laminate and a printed wiring board which have excellent adhesion, electric insulation, and resistance to heat, chemicals, and water, and which can be molded in a mild condition. SOLUTION: The polyimide composite consists of (A) a polyimide component and (B) other polymer components, and has an elastic modulus of less than 10 GPa. A varnish is made from this polyimide composite, a film is similarly made from the polyimide composite, and a metal-clad laminate is made by forming a layer of the polyimide composite on a metal foil. Furthermore, a printed wiring board uses at least one layer of the metal-clad laminate. |
