Provided is an ultrasonic probe possessing signal lines for which generation of the acoustic crosstalk between piezoelectric elements to each other constituting a piezoelectric element array, and also provided is a method of preparing the ultrasonic probe. Disclosed is an ultrasonic probe comprising a first piezoelectric element array in which first piezoelectric elements each as a both-sided electrodes-providing piezoelectric element are two-dimensionally arrayed; a second piezoelectric element array layered on the first piezoelectric element array; an acoustic separation section provided between the first piezoelectric elements to each other, arrayed in the first piezoelectric element array; and a signal line possessing a conductive layer coated on an outer circumferential surface of a core material and the core material having an acoustic impedance nearly equal to another acoustic impedance of the acoustic separation section, the signal line connected to the second electrode by passing through the acoustic separation section.
