PROBLEM TO BE SOLVED: To sufficiently enhance the joining strength between a first member and a second member by surely softening and melting both a first member side and a second member side of an intermediate member for laser joining.SOLUTION: In the joining method using laser light in which the intermediate member 3 for laser joining which has laser light absorptivity is interposed between the first member 1 having laser light permeability and the second member 2 having laser light absorptivity to join the first member 1 and the second member 2 through the intermediate member 3, the laser light absorptivity of the second member 2 is set to 60% or more, the laser light absorptivity of the intermediate member 3 is set to 40% or more and 60% or less, and the first member 1, the intermediate member 3 and the second member 2 are superposed with the intermediate member 3 being interposed between the first member 1 and the second member 2, and laser light is radiated from the first member 1 side. |
