摘要： PROBLEM TO BE SOLVED: To provide an array type ultrasonic probe with a stable characteristic and a fine high frequency without using a macromolecular piezoelectric film such as polyvinylidene fluoride which is low in relative permittivity and piezoelectric d 33 constant to be the cause of a low wave transmission sensitivity and low S/N and without performing a step to generate much loss such as slicing a brittle piezoelectric material such as PZT or conducting adhesion onto a substrate. SOLUTION: The array type ultrasonic probe includes: titanium electrodes arrayed on the substrate which is composed of a heat-resistant and corrosion-resistant material; and a piezoelectric film arranged on the titanium electrodes by a hydrothermal synthesis method. The probe is manufactured by coating a titanium film on the substrate composed of the heat-resistant and corrosion-resistant material by sputtering or chemical vapor deposition, patterning the titanium film in an array shape by a photolithography method, to form the titanium electrodes, and arranging the piezoelectric film on the electrodes by the hydrothermal synthesis method.
