Optical module

An optical module comprising:

• a mirror unit including a mirror device including a movable mirror portion provided with a coil;
• and
• a magnet unit including a first magnet, a second magnet, and a third magnet arranged along a first direction, and configured to generate a magnetic field acting on the movable mirror portion,
• wherein the mirror unit is disposed on the magnet unit in a second direction perpendicular to the first direction, and includes a bottom surface facing the magnet unit,
• a protrusion portion protruding to a magnet unit side is formed on the bottom surface,
• a width of the protrusion portion in the first direction is equal to or less than a width of the first magnet in the first direction,
• the mirror unit is fixed to an upper surface of the first magnet at the protrusion portion,
• the protrusion portion protrudes from the bottom surface of the mirror unit toward the magnet unit side, and
• in a cross-section taken along the first direction and passing through a center of the mirror device when viewed in the second direction, the protrusion portion is disposed so as to overlap with the upper surface of the first magnet in the second direction.
