Abstract
An optical pickup device comprises a light emitting element for emitting a laser beam, and a housing in which the light emitting element is mounted, wherein the light emitting element is contained in a holder for protecting the light emitting device, the holder including a projecting portion for dissipating heat generated by the light emitting element, and the projecting portion is located within the housing. Thus, an optical pickup device having a light emitting element held in a holder which is superior in heat dissipation and is resistant to damage can be provided.
