The ultrasonic probe and ultrasonic diagnostic apparatus

The present invention is a linear array transducer (transducer) that a plurality of the piezoelectric element and the piezoelectric element having a piezoelectric array of the sound wave is scanned in a fixed direction is formed on the first backing material; And a sound wave is a phased array transducer (transducer) formed on the plurality of the piezoelectric element and the piezoelectric element and the second backing material has a piezoelectric array is scanned to enable the steering according to the direction and depth; includes, where the linear array transducer and the phased array transducer may be characterized as being formed by bonding to each other.
