Metal/fiber-reinforced resin material composite

[Problem] To provide a metal/fiber-reinforced resin material composite in which a metal member and a fiber-reinforced resin material are firmly bonded, a light weight and excellent workability are obtained while the strength is enhanced, and the amount of the fiber-reinforced resin material used can be reduced. [Solution] A metal/fiber-reinforced resin material composite comprising a metal member, and a first fiber-reinforced resin material having a matrix resin and a reinforcement fiber material, the metal member and the first fiber-reinforced resin material being formed into a composite with an adhesive resin layer interposed therebetween, wherein the adhesive resin layer is obtained by solidifying or curing an adhesive resin composition containing at least 50 mass parts of a phenoxy resin (A), and the maximum load of the metal/fiber-reinforced resin material composite is greater than the total load of the maximum load of the metal member alone and the maximum load of the fiber-reinforced resin material alone (i.e., so as to display a “super-law-of-mixture (or law of over-mixture)” that surpasses the law of mixture with respect to the tensile load).
