Abstract
Disclosed is a composite metal sheet composed of at least two metal sheets and an intermediate resin layer interposed therebetween. The intermediate resin layer in composed of a mixture of an organic polymeric material resin and a metal powder (inclusive of an alloy powder) having a good electroconductivity, a hardness higher than that of the metal sheets, and an average particle size of 80 to 100% of the thickness of the intermediate resin layer. The amount of the metal powder is 1 to 10% by volume based on the intermediate resin layer (a sum of the resin and metal powder) and the metal powder is dispersed substantially uniformly in the intermediate resin layer. The composite metal sheet has excellent electric resistance weldability and adhesion strength.
