The optical element driving apparatus includes a voice coil motor moving an optical element in a first direction, and a magnetic sensor detecting a position of the optical element. A yoke of the motor includes a first yoke portion having a magnet attaching surface to which the magnet is attached and a second yoke portion disposed away from the first yoke portion in a second direction so as to form a space with magnet, allowing movement of a coil of the motor in the first direction. The second yoke portion is disposed closer to the magnetic sensor than the first yoke portion in a plane orthogonal to the first direction. In a third direction orthogonal to the first and second directions, a magnetic path width A of the second yoke portion and a width C of the magnet have the following relationship of A>C.
