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 thickness direction 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. An upper layer and a lower layer each sandwiching the electrodes formed on both surfaces of the reception element layer are each provided with a projecting portion which projects from the reception element layer in a direction of elevation. At least one of the electrodes formed on the reception element layer is formed by extending on a surface of one of the projecting portion opposed to a respective one of the upper layer and the lower layer.
