Joint structure (1) for a fiber reinforced resin (12,13,14,15) and a metal (11). In the structure (1), multiple single elements (10) are laminated such that the step-shaped structures are superposed in a thickness direction. Each joint structure (1) is constituted by a metallic material (11) including a step-shaped structure having an end portion that gradually becomes thinner towards an end surface thereof so as to form a step-shaped joint surface, and a fiber reinforced plastic (12,13,14,15) laminated such that an end portion thereof covers the step-shaped structure smoothly. The metallic material (11) and the plastic (12,13,14,15) are adhered, and adjacent elements are joined by superposed surfaces thereof. A main welding portion (16) is formed on an outer end of the metallic material (11) by welding mating surfaces of adjacent metallic elements(10). A secondary welding portion (17) is formed on the plastic side of the main welding portion (16) on all the metallic materials (11) by welding them in the thickness direction. |
