摘要
A vibrator of a vibration-type driving device according to an aspect of the present invention includes a first vibrating member that includes first protrusions protruding in a first direction, a second vibrating member that includes second protrusions protruding in a direction that is opposite to the first direction, and an electric-mechanical energy conversion element that is fixed to the first vibrating member. The first protrusions and the second protrusions each have a hollow structure, and the first vibrating member and the second vibrating member are disposed in such a manner that a surface of the first vibrating member on which the first protrusions are not formed and a surface of the second vibrating member on which the second protrusions are not formed face each other.
