1. An optical module comprising:
a support;
a movable part;
a connecting part connecting the movable part to the support so that the movable part is swingable about an axis;
a mirror provided to the movable part;
a drive coil provided to the movable part;
a temperature monitoring element; and
a magnet that generates a magnetic field acting on the drive coil, wherein
the support is thermally connected to the magnet,
a thermal conductivity of the support is 100 or more times higher than a thermal conductivity of air, and
the entire temperature monitoring element is disposed at a part other than the movable part and the connecting part.
