A manufacturing method of an ultrasonic probe includes analyzing a first lateral vibration which is superposed on a longitudinal vibration in a probe preparatory body when the probe preparatory is longitudinally vibrated because of an asymmetric shape of a distal asymmetric portion. The manufacturing method includes specifying a bending position to bend a symmetric portion so that a proximal side probe component located to a proximal-direction side of the bending position is parallel to the X-Y plane and tilted relative to the X-axis, a second lateral vibration, which has the same wavelength and vibration direction as the first lateral vibration and is in anti-phase with the first lateral vibration, being superposed on the longitudinal vibration and the first lateral vibration while the symmetric portion is bent at the bending position. |
