Here, the reflected luminous flux transmits through again the objective lens 8, the reflection surface 11a to be made incident on a transparent substrate 7. Further, a signal beam is diffracted in the C direction at a diffraction angle of 5-20 deg. by a light diffraction groove 10, and is led to a signal beam detection element 5, and an information signal is reproduced.  On the other hand, 20% of the luminous flux from the laser diode 4 is reflected in the D direction by the reflection surface 11a, and is reflected on the reflection surface 11b to be led to a monitor light detection element 6, and a light emission amount is controlled. In such a manner, the main element is integrally constituted to the integrated optical element, and the relative position adjustment is eliminated, and the number of parts are reduced, and the device is miniaturized.
