Optical module

An optical module comprising:

• a mirror unit including a mirror device including a movable mirror portion provided with a coil;
• a magnet unit having an upper surface, a bottom surface, and a side surface extending from the upper surface to the bottom surface, and configured to generate a magnetic field acting on the movable mirror portion;
• and
• a package including a recess accommodating the magnet unit,
• wherein the magnet unit includes a plurality of magnets arranged along a first direction,
• the recess includes a base wall portion which extends along the first direction and to which the upper surface of the magnet unit is fixed, and a side wall portion extending along a second direction intersecting the first direction, and facing the side surface of the magnet unit,
• when a side on which the magnet unit is located with respect to the base wall portion in the second direction is defined as a lower side, the recess includes an opening portion that is delimited by the side wall portion and open to the lower side,
• the mirror unit is disposed on a second surface on an opposite side of the base wall portion from a first surface to which the magnet unit is fixed, and
• the side wall portion protrudes to the lower side with respect to the bottom surface of the magnet unit.
