PROBLEM TO BE SOLVED: To provide a jointing method to perform jointing without damaging a sheet like member constituting a laminating material when a laminating material and a jointed material are jointed. SOLUTION: In this jointing method of a laminating material, an ultrasonic wave vibration is provided to a laminating material 1 having such a structure that sheet-like members are laminated and a jointed member 2 overlapped on the laminating material 1, so as to joint the sheet-like members of the laminating material 1, and the laminating material 1 and the jointed member 2. The jointed member 2 has a protrusion part 22 protruding at the overlapped part of the laminating material 1, and the ultrasonic vibration is provided under the condition that the protrusion part 22 presses the laminating material 1. Further, a protrusion part is formed on the jointing face of the jointed member against the laminating material 1, and an ultrasonic wave amplitude energy in an ultrasonic jointed method is locally absorbed and diffused, so as to make a process in the ultrasonic jointing to be a highly efficient.
