An ultrasonic probe includes at least one transmission element layer for transmitting ultrasonic waves, at least one reception element layer for receiving ultrasonic waves and which is provided with an electrode on each of both surfaces opposed in a direction of a thickness thereof, and at least one matching layer for matching acoustic impedance. These layers are arranged in this order in a direction of transmitting the ultrasonic waves. The reception element layer is provided with a projecting portion projecting in a direction of elevation from upper and lower layers which sandwich the two electrodes respectively formed on both surfaces of the reception element layer, and at least one of the electrodes is formed by extending to the projecting portion.
