Abstract
A contact member that makes it possible to reduce variations in characteristics of individual vibration actuators. The contact member is in contact with a vibration member. The contact member has a sintered body of metal powder as a base material. A contact surface of the sintered body, which is in contact with the vibration member, is formed by impregnated resin portions as pore portions of the sintered body in which resin has been impregnated, and non-impregnated as pore portions of the sintered body in which the resin has been impregnated. A ratio of the impregnated resin portions with respect to an entirety of the contact surface is 2% or more and 15% or less, and a ratio of the non-impregnated pore portions with respect to the entirety of the contact surface is 3% or more.
