By bonding a conductive first matching layer to the acoustic radiation surface side, which is the bottom side, of a belt-shape piezoelectric element on both faces with electrodes provided, and using a dicing machine to form divided grooves , an array of piezoelectric elements is formed in the element array direction. By deepening the divided grooves , generation of cross talk can be prevented, and by filling the portions of the divided grooves not in contact with the piezoelectric elements with a conductive adhesive , a reduction in strength due to formation of the divided grooves can be prevented, and a common connection between the ground electrode on the bottom surface of each piezoelectric element and the conductive first matching layer can be reliably secured.
