Joint structure for fiber reinforced resin and metal, and joining method for fiber reinforced resin and metal

A joint structure for a fiber reinforced resin and a metal, comprising:

• a fiber reinforced plastic;
• and
• a metallic material including an end portion joined via a step-shaped joint surface to an end portion of the fiber reinforced resin,
• wherein a plurality of single elements each constituted by the metallic material which includes a step-shaped structure having an end portion that gradually becomes thinner in a direction of an end surface of the end portion so as to form the step-shaped joint surface, and the fiber reinforced plastic which is laminated such that respective end portions thereof covers the step-shaped structure, are laminated such that the step-shaped structures are superposed in a thickness direction,
• wherein the metallic material and the fiber reinforced plastic are adhered to each other,
• wherein adjacent elements are joined to each other by superposed surfaces thereof, and
• wherein a thinnest portion of the metallic material is disposed on outer surfaces in a region of the step-shaped structure.
