Abstract
An ultrasonic probe including a piezoelectric vibrator and a layer, wherein the piezoelectric vibrator transmits and receives ultrasonic waves. The layer is connected to a rear surface of a side opposite a side receiving and sending ultrasonic waves from the piezoelectric vibrator and has an acoustic impedance and Young's modulus larger than that of the piezoelectric vibrator, and includes a plurality of grooves arranged such that the rear surface of the piezoelectric vibrator faces the grooves opening, wherein the plurality of grooves are shaped such that groove capacity occupying the layer volume is increased in a direction along a center to an end of the rear surface of the piezoelectric vibrator.
