The optical module includes a base, a first frame body disposed in the base, an optical element disposed in the first frame body, and at least one driving assembly disposed between the base and the first frame body. The first frame body is configured to swing relative to the base through a magnetic force generated by the at least one driving assembly, and each of the at least one driving assembly includes a coil and a magnetic structure that is separated from the coil and includes a magnetic permeable plate, a separation medium, and a magnet element. The separation medium is located on one side of the magnetic permeable plate facing the coil. The magnet element is disposed on the side of the magnetic permeable plate facing the coil and is separated by the separation medium.
