Abstract
With the ultrasonic adhering method and apparatus, ultrasonic adhesion can be made appropriately, regardless of external environments and a simple structure. The apparatus includes an ultrasonic oscillator for generating ultrasonic vibration, a horn provided in this ultrasonic oscillator for oscillating ultrasonically, and a temperature sensor for sensing the temperature of the horn. A controlling unit is provided for detecting the temperature of the horn and controlling oscillation time of the ultrasonic oscillator in a state of the horn being contact with an object to be adhered in such a manner that the oscillation time has a negative correlation with respect to the temperature of the horn.
