Abstract:
1. An ultrasonic probe comprising: (A) a piezoelectric element consisting essentially of a piezoelectric single crystal and having a first and second main faces and a first and second side faces; (B) a first electrode deposited on a substantial portion of the first main face, the first side face, and a part of the second main face of the piezoelectric element, and a second electrode deposited on a substantial portion of the second main face, the second side face, and a part of the first main face of the piezoelectric element, the first and second electrodes being isolated from each other by two grooves formed on the first and second main faces of the piezoelectric element, in a manner parallel to the side edges of the piezoelectric element, respectively, at positions separated from the second and first side edges by a given distance, respectively; (C) a backing layer attached to the electrode layer deposited on the second main face of the piezoelectric element; (D) a ground electrode attached to the first electrode at the first side face of the piezoelectric element; and (E) a flexible printed circuit board attached to the second electrode in the front of the groove positioned on the first main face, extending from the second side face, of the piezoelectric element, by the end part bended at a right angle.
