ABSTRACT:
An ultrasonic oscillator, comprises a group of internal electrodes divided into four approximately equal parts along two directions, i.e., a second direction which is perpendicular to a direction of layers as first direction, and a third direction which is also perpendicular to the first direction; and comprises an electrode connection-use conductor film which is formed along a face perpendicular to the aforementioned direction of layers for electrically connecting a predetermined external electrode among the first group of external electrodes and a predetermined external electrode among the second group of external electrodes, respectively.
