Patent ID: 7952980

Claim:
An optical pickup apparatus comprising: a polarization beam splitter fixed to a base, the polarization beam splitter including a first prism that laser light emitted from a laser diode enters, a second prism that return light of the laser light reflected from a signal recording layer of an optical disc enters, and a control film that is formed on either one of an opposed surface of the first prism and an opposed surface of the second prism so that the laser light incident on the first prism and the return light incident on the second prism are selectively passed through or reflected from the control film, the opposed surfaces being opposed to each other; a first positioning pin provided on the base so as to position the polarization beam splitter; and a second positioning pin provided on the base so as to position the polarization beam splitter, the polarization beam splitter being fixed to the base in a state where the opposed surface of at least one of the first prism and the second prism is made in contact with at least one of the first positioning pin and the second positioning pin.
