PROBLEM TO BE SOLVED: To provide a lamination structure joint body in which at least one layer of an intermediate layer member having a relatively low melting point is sandwiched between upper and lower layer members having a relatively high melting point, of metal, which can be joined by solid phase joint by heat, and a production method of the same.SOLUTION: The invention is a method for producing a lamination structure joint body in which at least one layer of an intermediate layer member 7 having a melting point lower than that of any one of upper and lower layer members 3, 5 of metal, and not capable of joining to at least any one of the upper and lower layer members by solid phase joint is sandwiched between the upper and lower layer members which can join each other by solid phase joint. A friction agitation joint tool 1 which rotates at high speed is pressed to the upper layer member 3 for softening it by frictional heat, and the tool is inserted for deforming the upper layer member 3, then the tool pushes aside the intermediate layer member 7 and reaches the lower layer member 5, so that the upper layer member 3 and the lower layer member 5 are joined by solid phase joint.SELECTED DRAWING: Figure 2 |
