Abstract
An ultrasonic probe serving as a sensor array used in a transmitting/receiving device includes a substrate made of a packing material. A plurality of piezoelectric vibrators shaped like a rectangular parallelepiped are fixed in a matrix on one principal surface of the substrate. Each of the piezoelectric vibrators includes a plurality of piezoelectric layers stacked in a direction that crosses two adjoining side faces of the piezoelectric vibrator at an angle of approximately 45°. Inner electrodes are formed between the piezoelectric layers, and outer electrodes are formed on both end faces of the piezoelectric layers.
