Abstract
An ultrasonic probe includes: a piezoelectric element that transmits and receives an ultrasonic wave; one or a plurality of acoustic matching layers disposed on a subject side of the piezoelectric element; and a conductor layer that applies a voltage to the piezoelectric element, wherein the conductor layer is disposed between the piezoelectric element and the acoustic matching layer, or between the plurality of acoustic matching layers, a magnitude of an acoustic impedance of the conductor layer is between a magnitude of an acoustic impedance of a layer disposed on one surface side of the conductor layer and a magnitude of an acoustic impedance of a layer disposed on the other surface side of the conductor layer, and the conductor layer has a Vickers hardness (Hv) of 50 or more and 600 or less.
