Abstract
An ultrasonic joining horn disclosed herein can generate ultrasonic vibration in a predetermined vibration direction and includes a base portion, a stand portion that rises from an upper surface of the base portion, and a pressure contact portion formed of a plurality of protrusions that protrude from an upper surface of the stand portion. Each of the protrusions is formed into a pyramid shape or a truncated pyramid shape, the protrusions are arrayed, and when viewed from top, at least a portion of a peripheral edge of a portion in which the protrusions are arrayed has a zigzag shape. The zigzag portion is formed along at least one of the vibration direction and a perpendicular direction to the vibration direction. The upper surface of the base portion has an exposed surface on which the stand portion is not formed.
