[Object] The purpose of the present invention is to provide a layered composite that is high in both flexural modulus and moldability. [Solving Means] Provided is a layered composite including a carbon-fiber-reinforced resin in which a chopped strand prepreg obtained by impregnating fiber in resin is oriented in such a manner as to exhibit pseudo-isotropic properties, and a steel plate that is layered on at least one surface of the carbon-fiber-reinforced resin and has a tensile breakage elongation φ of equal to or more than 20%, the flexural modulus in a flat plate state obtained in compliance with ASTM D-790 being equal to or more than 30 GPa.

Layered composite

A roughened plated sheet including a roughened plated layer having a roughened nickel plated layer and a zinc plated layer formed on at least one surface of a metal substrate in this order from the metal substrate side, wherein a ten-point average roughness Rzof a surface of the roughened plated layer, according to laser microscope measurement, is 3 μm or more, and the metal substrate is a steel sheet.
