Patent ID: 7885019

Claim:
A lens driving apparatus comprising at least a lens holder (i) which has an objective lens; and (ii) in which a coil for driving control is mounted on side surface thereof, either an adhesive surface of the coil and the side surface being a concavo-convex surface on which a concavo-convex part for controlling a flowing direction of a fluid adhesive, is formed, the concavo-convex part for controlling the adhesive which is injected from an upper side to a lower side in a vertical direction, not to flow toward a substantially central portion, being formed at each of both edges in a horizontal direction on the concavo-convex surface, the coil and the lens holder being integrally molded by the adhesive via the concavo-convex surface, wherein (i) a first convex part in a relatively long shape in a tracking direction and (ii) a second convex part in a relatively long shape in a focusing direction, are formed on the concavo-convex surface.
