1. A vibration-type actuator comprising:
a vibrator including an elastic body and an electromechanical transducer attached to a surface of the elastic body; and
a flexible printed circuit board having an electrode portion and attached to the electromechanical transducer,
wherein the elastic body has an attached portion to which the electromechanical transducer is attached and a protrusion having a contact portion and a standing portion between the contact portion and the attached portion,
wherein there is a space surrounded by the contact portion, the standing portion, and the electromechanical transducer, and
wherein no end portion of the electrode portion of the flexible printed circuit board is overlapped with the space in a direction perpendicular to the surface of the elastic body.
