PROBLEM TO BE SOLVED: To provide a composite structure which is constituted so that a metallic plate is held between resin structures different from each other in the thermal expansion coefficient and in which a strain, a crack or an unwelded portion is prevented, by a simpler method, from being generated in the resin structure when the metallic plate is welded to the resin structure.SOLUTION: A production method of the composite structure comprises a step of sticking the metallic plates 21, 22 respectively to the front surface and back surface of the resin structure 3 by a thermal welding method. In the concrete, the production method thereof comprises the steps of: arranging a first groove 81 and a second groove 82, which are extended toward the directions different from each other, on one joint surface of the resin structure 3; abutting the metallic plates 21, 22 respectively on the front surface and back surface of the resin structure; and heating the abutted positions so that the resin structure 3 is welded thermally to each of the metallic plates 21, 22. |
