Abstract
An objective lens driving apparatus includes an objective lens () collecting a light flux emitted from a light source on a optical disk (), and a lens holder () holding the objective lens (). The lens holder () includes a first bonding portion () and a second bonding portion () for holding the objective lens () by means of bonding. The objective lens () is fixed to the lens holder () by applying a first bonding adhesive () to the first bonding portion () to thereby bond the objective lens () thereto, adjusting an inclination of an optical axis of the objective lens () while causing the first bonding adhesive () to deform, and applying a second bonding adhesive () to the second bonding portion (). The second bonding adhesive () has a larger Young's modulus after curing than the first bonding adhesive ().
