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 composite 1 according to the present invention comprises a metal member 10, an insulating layer 30 arranged on at least part of a surface of the metal member 10 and comprising a first matrix resin 31 containing nonconductive fiber 32, and a CFRP layer 40 arranged on at least part of a surface of the insulating layer 30 and comprising a second matrix resin 41 containing carbon fiber 42, wherein, when viewing the surface of the metal member 10 from vertically above, the CFRP layer 40 is positioned at the inside of a region where the insulating layer 30 is present and an outer edge of the CFRP layer 40 and an outer edge of the insulating layer 30 are 0.2 mm or more apart. Due to this, it is possible to prevent electrolytic corrosion of the metal member.
