It is an object of the present invention to provide an optical pickup apparatus appropriate for the notebook PC that can prevent structural resonance of the lens holder by arranging the focus coil and the tracking coil in a way to stabilize the weight balance, enable the tilt servo, and be composed in an extremely reduced thickness. An optical pickup apparatus composed to adjust the irradiation position of light beam to an optical disk by displacing an objective lens through a driving control of a lens holder holding the objective lens with a moving coil method, wherein an objective lens driving section is composed by arranging and fixing focus coils 7a, 7b so that a pair of coil main bodies be symmetrical about the objective lens 4 arranged at the middle of the lens holder 4, and arranging a pair of tracking coils 8a, 8b, 8c, 8d at both sides of the respective focus coils.
