This camera actuator is provided with a stationary-side member, a movable-side member which is provided to the stationary-side member in a displaceable manner and which holds a lens section, and a drive section which displaces the movable-side member in a plane including a first direction and a second direction which is perpendicular to the first direction. The movable-side member has a magnet affixation section for affixing a magnet section thereto such that the magnet section faces the stationary-side member, the magnet section being used for detecting the position of the movable-side member in either the first direction or the second direction. The surface of the magnet affixation section, to which the magnet section is mounted, is formed from metal.
