Abstract
An optical pickup used in an optical recording and reproduction apparatus, wherein a wiring board formed with the wiring pattern has electrically connected to it a light receiving and emitting unit provided with a light emitting unit and an optical signal detection unit. At the same time, an object lens driving element is arranged on the wiring board. Due to this configuration, the electric connection members can be reduced and a reduction of size and a reduction of thickness of the optical pickup can be achieved.
