Abstract:
Disclosed is a vibration wave motor including: a vibrator provided with a piezoelectric element and a vibration plate; a frictional member having a frictional contact surface coming into contact with the vibrator; a fixing member having a recess to which the frictional member is fixed; and pressurizing unit that pressurizes the vibrator toward the frictional member, wherein the vibrator and the frictional member make relative movement using vibration generated from the vibrator, a fixing material for fixing the frictional member is provided between the frictional member and the fixing member, and the frictional member is fixed by coming into contact with the fixing member.
