In an ultrasonic probe to be used in an ultrasonic diagnostic apparatus for medical use, ultrasonic transducers are cooled while sufficiently absorbing ultrasonic waves released to the back of the ultrasonic transducers without causing attenuation of ultrasonic waves transmitted or received by the ultrasonic transducers. The ultrasonic probe includes: an ultrasonic transducer array including plural ultrasonic transducers for transmitting and receiving ultrasonic waves; an acoustic matching layer provided on a front of the ultrasonic transducer array; a cooling mechanism directly or indirectly provided on a back of the ultrasonic transducer array and including a porous member; a backing material provided on the back of the ultrasonic transducer array via at least the cooling mechanism; and channels for circulation of a liquid heat transfer material in the cooling mechanism.
