A vibration generation apparatus (1) includes a rod-shaped vibrator (400), a case (301) housing one portion of the vibrator (400), a magnet (303) and a yoke (302) disposed on one of the one portion of the vibrator (400) and an inner portion of the case (301), and a coil (308) disposed near the magnet (303) and the yoke (302) and on the other of the one portion of the vibrator (400) and the inner portion of the case (301). The other portion of the vibrator (400) exposed to the outside of the case (301) and the outer portion of the case (301) are connected through the elastic member so as to be able to approach and leave each other. Vibrations are generated by generating a force acting in an extending direction of the vibrator (400) using a current flowing through the coil (308) and a magnetic flux generated by the magnet (303) and the yoke (302) and causing the vibrator (400) and the case (301) to approach and leave each other using the generated force.
