Japanese Patent JP5095593
Kind Code:
B2
Abstract:
In an ultrasonic probe in which individual wires led out from multilayered piezoelectric elements are arranged in a staggered manner, short-circuit is prevented. Each of the elements includes: a multilayered structure in which piezoelectric material layers and at least one internal electrode are stacked; first and second flat electrodes; first and second side electrodes; an insulating film formed at a second side surface side of the multilayered structure; a wiring member bonded to the first flat electrode on the one end of the multilayered structure by using a conducting adhesive material; and the wiring member is provided at the second side surface side of the multilayered structure and the insulating film electrically separates the second side electrode and the conducting adhesive material in a first element, and the wiring member is provided at a first side surface side of the multilayered structure in a second element.
