Disclosed is an ultrasonic vibration device. The disclosed ultrasonic vibration device includes a case forming at least one installation hole on a bottom plate and having a receiving space unit; a piezoelectric unit mounted on the bottom plate and conducted by first and second terminals; a vibration unit formed on the case and delivering the vibration of the piezoelectric unit; and a joining unit integrally joining the case, piezoelectric unit, and the vibration unit. The purpose of the present invention is to provide the ultrasonic vibration device and an assembling method thereof capable preventing separation due to vibration to provide long lifetime and storing durability by arranging vibrating members each on the front and rear surfaces of the installation hole of the case and joining the vibrating members to the case using the joining unit instead of attaching the vibrating members vibrated by a piezoelectric element to the case using an adhesive. |
