PROBLEM TO BE SOLVED: To provide a part joiner capable of efficiently joining a larger part than conventional devices, and to provide an ultrasonic horn. SOLUTION: A plurality of fixed sections 7k fitted to both side faces 7h in the width direction of the ultrasonic horn 7 and fixed to a lifting-lowering member 6 are opposed in the width direction, and disposed at places holding a joining-work section 8b in the longitudinal direction. A pair of trenches 7p extending in the width direction while holding the root of the joining-work section 8b in the longitudinal direction is further formed between the fixed sections 7k close to the joining-work section 8b while holding the joining-work section 8b in the longitudinal direction.
