Patent ID: 8531178

Claim:
An ultrasound probe comprising: a plurality of inorganic piezoelectric elements for transmitting an ultrasound wave, wherein the plurality of inorganic piezoelectric elements are arranged with a first predetermined pitch in arrays, and wherein each of the plurality of inorganic piezoelectric elements is made of an inorganic piezoelectric material and has two opposing surfaces each provided with an electrode; and an organic piezoelectric element for receiving an ultrasound wave, wherein the organic element is made of a sheet-like organic piezoelectric material and is directly or indirectly laminated on and extends over the plurality of inorganic piezoelectric elements, wherein the organic piezoelectric element has two opposing surfaces each provided with an electrode, and wherein at least one of the electrodes of the organic piezoelectric element includes a plurality of electrodes which are separated from one another and arranged with a second predetermined pitch in arrays, wherein the first predetermined pitch with which the plurality of inorganic piezoelectric elements are arranged and the second predetermined pitch with which the plurality of electrodes provided on a surface of the organic piezoelectric element are arranged are different from each other.
