An optical pickup apparatus comprising a first objective lens that focuses first laser light on an information recording layer of a first optical disc in a first mounting state where the first optical disc is mounted on a turntable; a second objective lens that focuses second laser light on an information recording layer of a second optical disc in a second mounting state where the second optical disc is mounted on the turntable, the second optical disc having an information recording format different from that of the first optical disc; and a lens holder that integrally holds the first objective lens and the second objective lens in an adjacent manner on the outside and inside, respectively, along a radial direction of the first optical disc in the first mounting state and of the second optical disc in the second mounting state, the lens holder being shiftable along the radial direction, a disc surface of the first optical disc in the first mounting state and of the second optical disc in the second mounting state being substantially parallel to a confronting face of the first objective lens and of the second objection lens, that confronts the disc surface, a minimum distance bet ween the disc surface and the confronting face in a direction of a rotation axis of the turntable being greater than a thickness of the turntable in a direction of a rotation axis thereof.
