An optical pickup whose thickness is small and power consumption is low is provided, in which these advantages are achieved by increasing the driving force generated in the tilt coil in an objective lens driving apparatus and by making the thickness of the objective lens driving apparatus to be small. In an optical pickup including: an objective lens for condensing light onto an optical disc; a lens holder to which the objective lens has been attached; a focusing coli, a tracking coil, and a tilt coil, which have been attached to the lens holder; and a reflection mirror for reflecting light toward the optical axis of the objective lens, the tilt coil is made to have a shape in which the tilt coil is not brought into contact with the side of the reflection mirror, the side being near to the objective lens.
