<P>PROBLEM TO BE SOLVED: To improve durability by reducing the growth of voids ridges, or cracks in a welding member. <P>SOLUTION: An ultrasonic welding structure carries out the thermal welding of a heating object to a predetermined material to be joined by giving high-frequency vibration to the heating object from a horn 3, while pushing the horn 3 against a pillar-shaped heating object formed with a resin 10. The material to be joined has an insertion hole to insert the heating object, and the insertion hole of the material to be joined has a notch at the inside edge of the side which counters a resonator. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
