    摘要： The present invention provides a laminate comprising a resin layer and a copper foil. The resin layer is made from a liquid crystalline polyester having at least one structural unit selected from a structural unit derived from aromatic diamine and a structural unit derived from aromatic amine with a phenolic hydroxyl group in an amount of 10 to 35% by mole on the basis of the total structural units in the polyester. The copper foil has a tensile modulus of 60 GPa or smaller and a tensile strength at break of 150 MPa or smaller measured after heat treatment at a temperature of 300° C. The copper-foil laminate has good flexibility and high durability with little anisotropy is provided.
