PROBLEM TO BE SOLVED: To provide a highly accurate optical head which is small-sized and is excellent in assemblability for the purpose of optically recording and reproducing information to a disk-like recording medium. SOLUTION: In an integrated optical element 50, a heatsink 51 provided with a light source 1 and a photodetector 5 is installed with inclination to a holding substrate 54, through which this heatsink 51 penetrates, i.e., the heatsink 51 is installed with an optical axis of an irradiating laser beam tilted to a plane, on which a pattern of the holding substrate 54 is formed. |
