ABSTRACT:
A protective member is proposed which can reliably prevent damage to an optical disc and which can be easily mounted to an objective lens retaining portion of a pickup device. The objective lens protective member protrudes from the objective lens toward the optical disc. It has a resin film and a resin coating layer formed on the resin film by baking resin powder dispersed in an organic solvent, and an adhesive layer formed on the back thereof beforehand. Thus it is possible to reliably prevent damage to the optical disc and to easily provide the protective member on a retaining portion for the objective lens by bonding.
