Abstract:
This metal-carbon fiber reinforced resin material composite includes a metal member, a coating layer that is disposed on at least a part of a surface of the metal member and contains a resin, a carbon fiber reinforced resin material layer that is disposed on at least a part of a surface of the coating layer and contains a matrix resin and a carbon fiber material that is present in the matrix resin, and an electrodeposition film disposed so as to cover at least all of surfaces of the carbon fiber reinforced resin material layer, an interface between the metal member and the coating layer, and an interface between the coating layer and the carbon fiber reinforced resin material layer, in which an average film thickness A of the electrodeposition film formed on the surface of the carbon fiber reinforced resin material layer is 0.3 to 1.4 μm, and, at the time of immersing the metal-carbon fiber reinforced resin material composite in a 5 mass % sodium chloride aqueous solution with the electrodeposition film removed, an alternating impedance at a frequency of 1 Hz is 1×107Ω to 1×109Ω.
