An optical pickup is provided with a substrate on which a plurality of through holes are formed, wires whose base end sides are inserted through the through hole of the substrate, a lens holder supported on the front end sides of the wires, and a retaining member provided between the substrate and lens holder. The retaining member has laterally opened concave portions for filling a cushioning material and notch portions to communicate with these concave portions. The wires are disposed so as to be stored in the concave portions and are, at a lens holder-side surface of the substrate, soldered to the substrate.
