Disclosed is an ultrasonic probe wherein a bent section is constantly disposed within a projection plane of a probe main body section when the probe main body section is viewed along a longitudinal axis from a base end toward a leading end. The bent section has: a first bent surface that is bent with respect to the peripheral surface of the probe main body section such that the first bent surface extends close to the longitudinal axis and in contact with the longitudinal axis; a second bent surface that is bent with respect to the first bent surface, said second bent surface being bent in the bending direction of the first bent surface and in the direction to be away from the longitudinal axis; and a third bent surface, which is, with respect to the second bent surface, bent in the direction to be close to the longitudinal axis, said direction being the opposite direction to the bending direction of the first bent surface, and which extends toward an extending line of the first bent surface. The bent section has: a first treatment surface that is bent, with respect to the third bent surface, in the bending direction of the first bent surface; and a treatment part, which is positioned on the extending line or on the side opposite to the longitudinal axis with a boundary therebetween, said boundary being the extending line. |
