Classification: CPC B  H | IPC B  H

Claim 11:
12. A conductor joining method, the method comprising the steps of:
arranging a plurality of conductors in a space formed by a horn having a contact surface that is brought into contact with the conductors, and configured to ultrasonically oscillate, and a pair of regulating portions configured to be in contact with the contact surface, arranged so as to face each other at a predetermined interval, and configured to relatively move along the contact surface;
relatively moving the horn and the pair of regulating portions with respect to an anvil arranged at a predetermined interval with respect to the contact surface and moving at least one of the pair of regulating portions toward another of the regulating portions so as to sandwich the anvil between the pair of regulating portions facing each other, and compressing the conductors by the anvil and the horn with the pair of regulating portions sandwiching the anvil; and
performing ultrasonic welding the conductors compressed by the anvil and the horn by making the horn ultrasonically oscillate, wherein
on each of regulating surfaces facing each other in the pair of regulating portions,
a corrugated regulating portion in which a convex portion protruding toward another regulating surface facing the regulating surface, and a concave portion recessed in a direction opposite to a protruding direction of the convex portion are continuously provided along a facing direction in which the pair of regulating portions face each other and an orthogonal direction orthogonal to a movement direction in which the horn relatively moves with respect to the anvil is formed, and
an engaging concave portion and an engaging convex portion configured to engage with the convex portion and the concave portion are provided on a main surface facing in the facing direction of the anvil.
