Ultrasonic probe with a conductive substrate connected to a transducer

An ultrasonic probe, comprising:

• a piezoelectric transducer configured to send and to receive an ultrasonic wave;
• a conductive substrate for applying current to the piezoelectric transducer, wherein the conductive substrate is arranged oppositely to a side face of the piezoelectric transducer and has an end portion that is arranged outside of the side face of the piezoelectric transducer, the substrate further comprising a signal wiring and an earth wiring;
• first and second conductive materials arranged in first and second corner portions formed by the piezoelectric transducer and the conductive substrate, the conductive material electrically connecting the piezoelectric transducer to the conductive substrate;
• and
• a nonconductive material arranged on the side face of the piezoelectric transducer between the first and second corner portions, the nonconductive material insulating the first corner portion from the second corner portion.
