Abstract
An ultrasonic probe has strip-formed oscillators formed of a piezoelectric crystal material arranged in an array form. Metal layers are formed by a first layer of at least one of Ti, Ni and Cr, a second layer of at least one of Cu and Ni, and a third layer of at least one of Cu, Au, Pt, Ag and Pd. A backing material is fixed to the oscillators through the metal layers. With this structure, it is possible to manufacture an ultrasonic probe having a high sensitivity while maintaining a favorable dicing process, even while using a backing material having a low acoustic impedance and soft properties.
