PROBLEM TO BE SOLVED: To provide a bending vibration actuator which is used for acoustic vibration and for tactile vibration, is small-sized, excellent in vibration characteristics, and further has simple structure. SOLUTION: A bending vibration actuator includes: an acoustic vibrator comprised of a shim for holding an acoustic piezoelectric element in an elongated and thin shape and a tactile vibrator comprised of a base plate for holding a tactile piezoelectric element in an elongated and thin shape. A bending vibrator holding part is held at one end side of the base plate, and the bending vibrator holding part holds one end side of the shim of the acoustic vibrator. COPYRIGHT: (C)2011,JPO&INPIT
