Abstract
A vibration actuator, which can be stably driven and has high durability, is provided with a vibrating body having an elastic body, including a ferrous metal, and an electro-mechanical energy conversion device bonded to the elastic body, and a driven member frictionally contacting the vibrating body and moving relatively with respect to the vibrating body. The elastic body has a nitrided layer contacting the driven member, and the elastic body is electrically grounded without going through a nitrided layer.
