[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).

A joint structure includes: a first same-type metal member; a second same-type metal member that can be mutually welded with the first same-type metal member; and a different-type member that has a penetrating portion, is interposed between the first same-type metal member and the second same-type metal member. In the plate thickness direction of an emission region in which a laser beam is emitted toward the penetrating portion, the plate thickness at the emission region of the first same-type metal member positioned on the side on which the laser beam is emitted is a predetermined thickness corresponding to a first gap. The first same-type metal member and the second same-type metal member are fused and bonded together via the penetrating portion, and the different-type member is compressed and fixed, such that the different-type member is fixed to the first same-type metal member and the second same-type metal member.
