PROBLEM TO BE SOLVED: To provide a spherical multi-channel piezoelectric vibrator which is easily manufactured.SOLUTION: A spherical multi-channel piezoelectric vibrator 1 is a composite body of piezoelectric vibrator units 8, each of which having electrode layers 3 and 4 on upper and lower surfaces, which are arrayed in two dimension, and includes a spherical multi-channel piezoelectric vibration plate 9 formed spherically by protruding from a lower surface side, and an upper side electrode lead foil 12 attached to an upper side surface of an upper side electrode layer 3 of the multi-channel piezoelectric vibration plate 9 (here, at the upper side electrode lead foil 12, an extension part 12a is formed which extends outways from respective sides of the spherical multi-channel piezoelectric vibration plate 9 to cover at least a portion of the side surface of a sound absorbing material layer 10, and an adhesive layer is attached to the surface of the extension part 12a of the upper side electrode lead foil 12). A plurality of spherical multi-channel piezoelectric vibrators 1 are arrayed in two dimension in the direction along the surface of the spherical multi-channel piezoelectric vibration plate 9, and the multi-channel piezoelectric vibrators 1 adjoining each other are electrically connected together through the adhesive layer which is attached to the surface of the extension part 12a of the respective upper side electrode lead foils 12, to form a spherical compound multi-channel piezoelectric vibrator.
