This vibration actuator is provided with: an electric machine conversion unit for converting electrical power to mechanical vibration; a transmitting element for transmitting vibration from the electric machine conversion unit, as driving force; and an abutting element which abuts against the transmitting element and is moved by the driving force in a manner relative to the transmitting element, at least 2% of the surface of contact between the transmitting element and the abutting element being the proportion of the pore surface area on one of either the transmitting element or the abutting element. In this vibration actuator, the mean surface area of the pores may be at least 3 µm2. In the other of the transmitting element and the abutting element, the surface of contact with the mating element may contain iron. |
