The invention has a structure, in an acoustic lens for an ultrasonic probe comprising leg portions which are connected by a planar shape, and a lens portion which is provided on the leg portions and has curvature in the lengthwise direction, wherein the leg portions are made from an attenuation prevention material having the less ultrasonic propagation loss than for the lens portion. Moreover, the leg portions of the acoustic lens are formed with opposite end sides thereof in a bent L-shape. Furthermore, an ultrasonic probe is constructed by adhering onto a piezoelectric element group where a plurality of piezoelectric elements are arranged side by side, an acoustic lens provided with curvature in the lengthwise direction.
