PURPOSE: A probe and ultrasonic diagnostic equipment thereof are provided to selectively use a proper transducer by establishing a plurality of transducers generating an ultrasonic wave which has a different frequency band in a probe. CONSTITUTION: A probe(150) comprises a first transducer(160), a second transducer(170), and a first transducer selecting unit. The first transducer is installed in a housing(190). The first transducer transmits an ultrasonic signal which has a predetermined frequency band to an object. The first transducer receives an ultrasonic echo signal reflected from the object. The first transducer includes a piezoelectric layer, a matching layer, and a lens layer. The second transducer is installed in a housing which is same as the first transducer. The second transducer is arranged in the first transducer in a row. The first transducer selecting unit selects the first transducer and the second transducer.
