Claim 10:
11. A conductor joining device for joining a plurality of conductors by ultrasonic welding, the conductor joining device comprising:
a horn having a contact surface that is brought into contact with the conductors and configured to ultrasonically oscillate;
an anvil configured to relatively move in a movement direction of approaching to or separating from the contact surface; and
a pair of regulating portions configured to be in contact with the contact surface and configured to be relatively movable along the contact surface, wherein
the regulating portions have regulating surfaces that face each other, and
in a case where a direction in which a pair of the regulating surfaces face each other is referred to as a facing direction, and a direction orthogonal to the movement direction is referred to as an orthogonal direction,
on at least one of the regulating surfaces, a corrugated regulating portion in which a convex portion protruding toward another regulating surface facing the one regulating surface, and a concave portion recessed in a direction opposite to a protruding direction of the convex portion are continuously provided along the orthogonal direction is formed
on a main surface facing in the facing direction of the anvil,
an engaging concave portion and an engaging convex portion configured to engage with the convex portion and the concave portion are provided along the orthogonal direction, and
at least one of the pair of regulating portions with respect to the anvil moves toward another of the pair of regulating portions so as to sandwich the anvil between the regulating portions facing each other, and the horn relatively moves with respect to the anvil.
