ABSTRACT:
An ultrasonograph, an ultrasonic transducer, an inspection device, and an ultrasonic imaging device enabling easy and quick inspection and high-resolution or high-speed processing are provided. Barium titanate (BaTiO3) or lead zirconate titanate (PZT) is used for a piezoelectric material constituting the ultrasonic transducer, and the thickness thereof is 0.1 μm to 100 μm. Included therein are a drive section capable of driving an arbitrary one of piezoelectric layers, a detecting section detecting electrical signals generated by the plural piezoelectric layers based on echoes from an inspection object, the echoes being originated from an ultrasonic wave generated by the driven piezoelectric layer, and a processing section performing processing for visualizing a state of the inspection object based on the detected electrical signals.
