摘要： Provided is a vibration actuator including: an electromechanical transduction member that transduces electric power to a mechanical vibration; a transmission member that transmits the vibration from the electromechanical transduction member as a driving force; and an abutting portion that abuts on the transmission member and moves relative to the transmission member in response to the driving force. One of the transmission member and the abutting portion includes pores in its surface contacting the abutting portion or the transmission member at an area occupancy of 2% or higher. In this vibration actuator, the average area of the pores may be 3 μm2 or larger. The other of the transmission member and the abutting portion may include iron in its surface contacting the one.
