Abstract
Provided is an ultrasonic probe, which can be improved in quality, which can acquire characteristics of a high sensitivity and a wide band and which can acquire an ultrasonic image of a high resolution. In this ultrasonic probe, grooves (160) are formed and utilized to form piezoelectric elements (110) and first acoustic matching layers (121) in a curved shape thereby to converge ultrasonic waves without any acoustic lens. Moreover, signal conductors (150) are disposed on the signal electrode faces of the piezoelectric elements (110).
