Provided are an ultrasonic probe and an ultrasonic diagnostic apparatus, which reduce parastic impedances which occurs in upper electrodes and lower electrodes, thereby reducing cross talk. The ultrasonic probe comprises a cMUT chip (20) having a plurality of transducer elements, an acoustic lens (26) on the ultrasonic wave irradiation side of the cMUT chip (20), a backing layer (22) on the back of the cMUT chip (20), and wires connected with the cMUT chip (20). This cMUT chip (20) includes a plurality of upper electrodes (46) and a plurality of lower electrodes (48), and these lower electrodes (48) are connected at two or more portions with wires.
