Abstract
A horn that can suppress oscillation components other than the component in the horizontal direction, a horn unit, and a bonding apparatus using same are provided. The horn has a cross-section variable section in which a cross section perpendicular to the lengthwise direction (X direction) thereof has a first region extending in the Z direction and a pair of second regions sandwiching the first region from Y direction. In the position Pcorresponding to an anti-node of a standing wave of oscillations excited in the horn, a sectional area Sof the first region assumes a maximum and a sectional area Sof the second region assumes a minimum. With a transition from the position Pto the other positions corresponding to nodes, the sectional area Sdecreases and the sectional area Sincreases. As a result, oscillation components other than those in the X direction are suppressed.
