ABSTRACT:
A laser scanning device having a light emitting element, an optical element for shaping a laser beam emitted from the light emitting element, a radiator which holds the light emitting element, and a holder to which the radiator and the optical element are fixed. The radiator is planar extending from a flange of the light emitting element. The radiator and the holder are located with a specified space in-between, and resin columns are placed in the specified space. After the radiator holding the light emitting element is positioned in relative the holder in three axial directions, the resin columns are hardened. After the resin columns are hardened, the holder is fixed in a housing.
