Abstract
A power supply device adapted to supply power to a pair of electrodes formed on opposite end surfaces of an ultrasonic vibrator. The device has a circuit layer arranged on a flexible base. The circuit layer has a pair of supply electrodes arranged at its one longitudinal end and a pair of end connections arranged at the other longitudinal end. A pair of conductive layers electrically connect the supply electrodes and the end connections, respectively. Each supply electrode has an inner surface of substantially the same shape as the end surface of the ultrasonic vibrator, the inner surface being joined electrically and mechanically with the electrode of the ultrasonic vibrator. The flexible base has an electrode base covering an entire outer surface of each of the supply electrodes, and a circuit base holding the conductive layers. A shield layer may be disposed on the flexible base in order to screen electromagnetic radiation from the circuit layer.
