An anti-shake apparatus of a photographing-apparatus comprises a movable-unit and a fixed-unit. The movable-unit has an imaging device, and is movable in a first-direction which is perpendicular to an optical axis of the photographing-apparatus, and performs an anti-shake operation by moving in the first-direction. The fixed-unit slidably supports the movable-unit in the first-direction. The movable-unit has first and second hall-elements which are used for detecting a position of the movable-unit in the first-direction as a first location, in order to calculate a detected-position signal. The fixed-unit has first- and second-magnets which are used for detecting the first location. The first hall-element faces the first-magnet in a second-direction which is perpendicular to the first-direction and the optical axis. The second hall-element faces the second-magnet in the second-direction. The detected-position signal is calculated on the basis of an average value between output values of the first and second hall-elements.
