摘要
A vibration type actuator uses a friction material of which a depth of impregnation with a resin can be easily measured in a non-destructive manner. The vibration type actuator has a vibrating body including an electro-mechanical energy conversion element and an elastic body; and a contact body configured to come into contact with the vibrating body. The vibration type actuator has a structure in which at least one of a friction portion of the contact body coming into contact with the vibrating body and a friction portion of the vibrating body coming into contact with the contact body has a metallic portion including a pore that is impregnated with a resin containing a fluorescent material.
