1. An optical element driving apparatus, comprising:
a coil and a magnet separately disposed at a movable part configured to hold an optical element and a fixing part configured to support the movable part, the coil and the magnet being configured to operate in conjunction with each other to move the movable part with respect to the fixing part; and
a magnetic sensor mounted on a magnetic sensor substrate and configured to detect a position of the movable part based on a relative position with respect to the magnet, wherein:
the fixing part is provided with a first recess and a second recess configured to house the magnetic sensor substrate and the coil, respectively, and
the first recess is formed in a part of a bottom part of the second recess with a depth equal to or greater than a thickness of the magnetic sensor substrate.
