Abstract
A vibration wave motor includes a vibrator including a piezoelectric element; a friction member with which the vibrator comes into contact by receiving pressurizing force; and a guide member that holds the vibrator. The guide member includes an input portion on one end portion, the input portion receiving force from outside, and a pressurizing portion on another end portion positioned on an opposite side of the one end portion, the pressurizing portion providing the pressurizing force to the vibrator. A guide portion extending in a direction of relative movement of the vibrator and the friction member is formed between the input portion and the pressurizing portion.
