A laminate includes a metal layer which is formed on and covers a surface of an insulating substrate activated by a plasma treatment by any method selected from a sputtering method, a vacuum depositing method and an ion plating method. The substrate is obtained by molding a resin composition containing 20 to 150 parts by mass of a fibrous filler having an average fiber diameter of 0.1 to 5 μm and an average fiber length of 10 to 50 μm relative to 100 parts by mass of a base resin comprising a thermoplastic resin and a thermosetting resin.

What is claimed is: 1. A laminate comprising a copper layer which covers the surface of an insulating substrate, which substrate is activated by nitrogen plasma treatment and which copper layer is formed on said substrate by sputtering, vacuum depositing or ion plating, wherein said substrate is obtained by molding a base resin selected from the group consisting of an aromatic polyamide and a liquid crystal polyester containing 20 to 150 parts by mass of a fibrous filler selected from the group consisting of boric aluminum and potassium titanate having an average fiber diameter of 0.3 to 1.0 μm and an average fiber length of 10 to 30 μm relative to 100 parts by mass of the base resin. 2. The laminate according to claim 1, wherein the aromatic polyamide is poly(phthalamide). 3. The laminate according to claim 1, wherein the liquid crystal polyester is a melt-type liquid crystal polyester. 4. The laminate according to claim 1, wherein said substrate comprises a core layer containing no fibrous filler and a superficial layer containing said fibrous filler. 5. The laminate according to claim 4, wherein said core layer contains powdery filler. 6. The laminate according to claim 1, wherein said substrate comprises a plurality of resin layers containing said fibrous filler. 7. The laminate according to claim 6, wherein the orientation direction of said fibrous filler is different between adjacent layers. 8. The laminate according to claim 7, wherein said orientation direction of said fibrous filler is orthogonal between adjacent layers.
