<p>PROBLEM TO BE SOLVED: To provide an ultrasonic bonding method to improve a connecting strength. SOLUTION: The ultrasonic bonding method has the step of bonding a first resin component 3 formed with a pin 5 to a second resin component 4 formed with a hole 6 to be inserted with the pin 5 by using an ultrasonic horn 1 for transmitting an ultrasonic vibration. In this case, the method comprises a step of positioning the component 3 with the component 4 by inserting the pin 5 into the hole 6 and a step of bonding the component 3 to the component 4 by both melting and caulking the pin 5 and ultrasonic welding at a pin periphery 7. The melting, the caulking and the welding may be simultaneously or sequentially executed with any first.</p> |
