An ultrasonic probe comprising an acoustic lens (20) having a concave lens surface (21) formed on one side of a lens body, and a piezoelectric transducer (23) disposed on the other side of the acoustic lens, ultrasonic waves generated by applying voltage to the piezoelectric transducer being focused through the lens surface to detect the reflected waves of the ultrasonic waves from a sample (26) by the piezoelectric transducer for obtaining information about the surface or interior of the sample. The lens surface (21) of the acoustic lens (20) is defined by an etch profile (15) formed by etching a substrate material (11) which makes up the lens body.
