ABSTRACT:
A lens drive apparatus for use in an optical pick-up apparatus, in which a bending mirror reflects an incident light flux from a light source and an objective lens converges the reflected light flux onto an optical disc through an objective lens, the lens drive apparatus includes: a base; a holder which holds the objective lens, being capable of moving with respect to the base; a pair of coils provided to interpose the objective lens held by the holder; and a pair of magnets attached to the base to face the pair of coils, respectively. The holder includes at least one surface which faces the incident light flux from the light source, among surfaces opposing to the pair of magnets, is shifted inwardly with respect to a surface of the holder that is close to the objective lens.
