Abstract
A matrix type ultrasonic probe is disclosed, which has a backing material, and a plurality of piezoelectric elements having upper and lower face electrodes, respectively, and arrayed in two-dimensional directions on the backing material. The ultrasonic probe further has first mounts provided for every piezoelectric element and fixedly secured to the backing material, signal lines provided for every piezoelectric element and embedded in the backing material to be exposed on the surface of the respective first mounts, and second mounts provided for every piezoelectric element to be fixedly secured to the lower face of the piezoelectric element and formed therein with through-holes. The first and second mounts are fixedly secured to one another by means of conductive adhesive, and the signal lines and the lower face electrodes are electrically connected to one another by means of the conductive adhesive.
