PROBLEM TO BE SOLVED: To provide an ultrasonic probe in which the whole region of an array- shaped vibrator group displays a uniform required sensitivity and whose reliability is high by a method wherein a front plate or a backing material is not stripped, deformed and damaged even when a vibrator, a damping material, the front plate and a bonding material whose coefficient of thermal expansion is different are selected and even when the bonding material whose melting point is high is used. SOLUTION: In an ultrasonic probe, a front plate 4 for protection is bonded,to the ultrasonic transmission-reception face of an array-shaped vibrator group 2 in which a plurality of vibrators 1, 3 are arranged in an array shape, and a clamping material 3 for residual-vibration suppression is bonded to the rear which is faced with the ultrasonic transmission-reception face. The ultrasonic probe is provided with side-part bonding materials 12 by which side edge parts 13a of the respective vibrators 13 at both ends of the array-shaped vibrator group 2 are bonded to the front plate 4. |
