Abstract
The invention has as its object the provision of a metal-fiber reinforced plastic composite able to more reliably prevent occurrence of an electrolytic corrosion action when forming a composite of a metal member and a fiber reinforced plastic layer comprising reinforcing fiber (carbon fiber) and a matrix resin. A metal-fiber reinforced plastic compositeaccording to the present invention comprises a metal member, an insulating layerarranged on at least part of a surface of the metal memberand comprising a first matrix resincontaining nonconductive fiber, and a CFRP layerarranged on at least part of a surface of the insulating layerand comprising a second matrix resincontaining carbon fiber, wherein, when viewing the surface of the metal memberfrom vertically above, the CFRP layeris positioned at the inside of a region where the insulating layeris present and an outer edge of the CFRP layerand an outer edge of the insulating layerare 0.2 mm or more apart. Due to this, it is possible to prevent electrolytic corrosion of the metal member.
