An ultrasonic probe includes: a transducer; a driving element electrically coupled to the transducer; a backing layer provided underneath the transducer and the driving element in a longitudinal direction of the ultrasonic probe, and configured to absorb heat generated from the transducer and the driving element and to absorb vibrations generated by the transducer; a heat spreader provided underneath the backing layer in the longitudinal direction of the ultrasonic probe and configured to absorb the heat from the backing layer; a heat pipe including a first contact portion contacting the heat spreader and a second contact portion in contact with the first contact portion; and a heat radiation plate configured to contact the second contact portion and transfer the heat from the heat spreader to an exterior of the ultrasonic probe.
