PROBLEM TO BE SOLVED: To achieve miniaturization and to stably hold a lens in a stop position. SOLUTION: A lens driving device 10 includes a driving magnet 31 which moves a moving lens 20 holding the lens 21 in an optical axis 11 direction and is fixed to the moving lens 20, a first driving coil 34 which is arranged on an ordinary photographing position side, and a second driving coil 32 which is arranged on a macrophotographing position side. When the energization to the first driving coil 34 and the second driving coil 32 is stopped, the driving magnet 31 is magnetically attracted to hold the moving lens 20 in the ordinary photographing position and the moving lens 20 is moved to the optical axis 11 direction by the energization to at least either of the first driving coil 34 and the second second driving coil 32. When the moving lens 20 moves to the macrophotographing position, at least either of the first driving coil 34 and the second driving coil 32 is energized and the moving lens 20 is held in the macrophotographing position.
