Abstract
A laminate comprising a metallic foil and a layer made of a liquid crystal polyester resin composition comprising a liquid crystal polyester(A) as a continuous phase and rubber(B) having a functional group reactive with the liquid crystal polyester as a dispersed phase. The laminate has excellent flexibility and electric properties, and additionally is cheap, therefore, suitable as a print wiring board. The laminate comprising a metallic foil, a layer made of a liquid crystal polyester resin composition and a layer made of a fiber material of the present invention has an excellent heat resistance, a low relative dielectric constant and a low dielectric loss tangent, an excellent appearance, and additionally, the laminate can be produced in an industrially inexpensive and simple manner. The laminate can be widely used in the industrial field for electric and electronic parts, precision parts and the like.
