Abstract: PURPOSE:To improve the recessed form on the sound pressure distribution in the short axis direction of the ultrasonic wave to be sent by the attenuation of the ultrasonic wave by an acoustic lens and to improve the directivity in the ultrasonic probe focusing the ultrasonic beam in the direction (short axis direction) to be crossed at right angles in a vibrator alignment direction by a projected acoustic lens. CONSTITUTION:A thin film member 3 with the low acoustic impedance at the center in the short axis direction between an alignment vibrator section 1 and a backing member 3 and with the higher acoustic impedance as it goes to the end section is provided. Thus, the effective impedance of the backing member sewing from a piezo-electric vibrator 11 becomes low at the center and becomes high as it goes to the end section. On the other hand, the vibration effeciency of the vibrator 11 becomes high at the center and becomes low as it goes to the end section. Thus, the sound pressure distribution forms a projected shape. As the sound pressure distribution becomes projected in the short axis direction, the focusing effect of the acoustic lens is not damaged and the directive characteristic is improved. Thus, a good image can be obtained and the S/N can be improved.
