Abstract:
An optical module includes a support, a movable part supported by the support so as to be swingable about an axis, a mirror provided to the movable part, a drive coil provided to the movable part, a temperature monitoring element provided to the support, and a magnet that generates a magnetic field acting on the drive coil. The support is thermally connected to the magnet.
