Abstract
The present invention relates to an ultrasonic probe comprising a group of piezoelectric elements consisting of a plurality of piezoelectric elements of a narrow card shape arrayed in a long-axis direction thereof and a rotational mechanism that rotates and oscillates said group of piezoelectric elements to the left and right in a short-axis direction thereof about the center of said long-axis direction; wherein said rotational mechanism is provided with a first bevel gear having teeth in at least an arc shape, a second bevel gear meshing with said first bevel gear and rotating in the horizontal direction, and a drive motor that rotates said second bevel gear; and also at least one of said first bevel gear and said second bevel gear is made of a synthetic resin.
