Abstract
A resonator for joining metal members utilizing ultrasonic vibration includes an ultrasonic horn having a length of at least half wavelength of a resonance frequency of ultrasonic vibration transmitted from a vibrator, and a joining tool provided on the ultrasonic horn so as to project in a direction normal to a vibration transmission direction of the ultrasonic horn at a position of a point of a maximum vibration amplitude of the ultrasonic horn. The joining tool is formed into a linear bar made of a material excellent in acoustic property and is provided on a distal end thereof with a tool head projecting laterally.
