摘要： PROBLEM TO BE SOLVED: To eliminate a fear of peeling at a joint position, to enhance yield and to improve reliability by providing a part with average coarseness different from the periphery on at least one substrate among plural substrates. SOLUTION: This optical pickup is provided with a λ/4 plate between a beam splitter film 35 and a recording medium 27, and outgoing light being linearly polarized light of an S polarization component is converted to the circularly polarized light to be made incident on the beam splitter film 35. Thus, since the light reflected by the recording medium 27 is guided to a photodetector 36 nearly by 100%, the reflectance of the S polarization of the beam splitter film 35 is enhanced remarkably, and the light quantity irradiating the recording medium 27 is enlarged. That is, the recording medium 27 is irradiated by a limited output of a light source 1 efficiently, and the reflection light from the recording medium is guided to the photodetector 37 efficiently.
