Abstract:
1. An ultrasonic probe including plural multilayered piezoelectric elements arranged in a row, each of said plural multilayered piezoelectric elements comprising: a multilayered structure in which plural piezoelectric material layers and at least one internal electrode are alternately stacked; a first flat electrode formed on a piezoelectric material layer located on one end of said multilayered structure; a second flat electrode formed on a piezoelectric material layer located on the other end of said multilayered structure; a first side electrode formed on a first side surface of said multilayered structure and connected to odd-numbered electrodes of said first and second flat electrodes and said at least one internal electrode, said odd-numbered electrodes including said first flat electrode; a second side electrode formed on a second side surface of said multilayered structure and connected to even-numbered electrodes of said first and second flat electrodes and said at least one internal electrode; an insulating film formed at a second side surface side of said multilayered structure; a wiring member bonded to said first flat electrode on said one end of said multilayered structure by using a conducting adhesive material; wherein said wiring member is provided at the second side surface side of said multilayered structure in a first multilayered piezoelectric element of said plural multilayered piezoelectric elements, said wiring member is provided at a first side surface side of said multilayered structure in a second multilayered piezoelectric element adjacent to said first multilayered piezoelectric element of said plural multilayered piezoelectric elements, and said insulating film electrically separates said second side electrode and said conducting adhesive material in said first multilayered piezoelectric element.
