A fiber-optic interferometric voltage sensor with high sensitivity is investigated. The fiber-optic voltage sensor is composed of an In-Line Michaelson interferometer bonded on a PZT. The In-Line Michaelson interferometer is a hollow optical fiber spliced to a single-mode fiber at one end and cleaved at the other end. The phase shift of the sensor output signal was induced by the applied AC voltage. The relation between the amplitude of the applied voltage and the phase shift of the sensor output signal was approximately linear and the sensitivity was $0.065{\pi}$ radian/V.
