ABSTRACT:
In an optical component where fixation of resin welding is performed by emitting a laser beam to screwing parts of an inner lens barrel and an outer lens barrel after focus adjustment, the laser beam is emitted to melt and cure a joint of the screwing part of the inner lens barrel and the screwing part of the outer lens barrel by 0.5 mm to 3.0 mm in a direction parallel to a direction of protrusion of the inner lens barrel relative to the outer lens barrel, so that welding and fixation are completed.
