An ultrasonic probe includes a multiple-members vibrating portion including a plurality of coupled vibration members which are connected with respect to each other, and each of which extends along the longitudinal axis between a first anti-node position and a second anti-node position of an ultrasonic vibration. The ultrasonic probe includes a groove defining portion which defines a groove in each of the coupled vibration members, each of the groove cooperating with a groove of the other coupled vibration member, and thereby forming at least a part of a passage inside the multiple-members vibrating portion. |
