PROBLEM TO BE SOLVED: To provide an optical pickup device generating laser beams having different wavelengths, which is capable of reducing the deviation of the optical axis of light which is emitted from plural elements and reflected by a prism to improve the yield and capable of attaining cost reduction. SOLUTION: The prism 32 is provided with wavelength selective reflecting surfaces 106, 107 corresponding respectively to plural laser elements 30, 31, and these reflecting surfaces are arranged in parallel to each other. Plural laser elements 30, 31 are arranged in the same side to the prism 32. |
