Abstract
What is provided is a new and improved metal-carbon fiber reinforced resin material composite in which the galvanic corrosion of dissimilar materials of a metal member is suppressed and electrodeposition coatability is excellent and a method for manufacturing the metal-carbon fiber reinforced resin material composite. A metal-carbon fiber reinforced resin material composite according to the present invention has a metal member, a resin coating layer disposed on at least a part of a surface of the metal member, and a carbon fiber reinforced resin material containing a matrix resin and a carbon fiber material present in the matrix resin, the resin coating layer contains any one or more kinds selected from the group consisting of metal particles, intermetallic compound particles, conductive oxide particles, and conductive non-oxide ceramic particles as conductive particles and further contains a binder resin, and the conductive particles have a powder resistivity at 23° C. to 27° C. of 7.0×10Ω·cm or less and contain one or more selected from the group consisting of Zn, Si, Zr, V, Cr, Mo, Mn, and W.
