PROBLEM TO BE SOLVED: To provide a method which is simple and is suitable for mass- production and spuriously makes the interval of light emitting points of plural semiconductor lasers proximate to each other by utilizing reflection surfaces in a module for intergrated optical pickup. SOLUTION: This module for intergrated optical pickup is constituted so as to contain the plural semiconductor lasers 5-3 and an optical element 5-4 having the plural reflection surfaces corresponding to the respective semiconductor lasers and, therein, is constituted in such a manner that the angles between heterozygous surfaces of the semiconductor lasers 5-3 and the corresponding reflection surfaces of the optical element 5-4 become respectively nearly perpendicular. This module for intergrated optical pickup is further constituted in such a manner that the two semiconductor lasers 5-3 are arranged opposite to each other, the optical element 5-4 which has the plural reflection surfaces corresponding to the respective semiconductor lasers are disposed between the semiconductor lasers and the reflection surfaces of the optical element are disposed respectively with an angle 45 deg. with respect to the optical axes of the corresponding semiconductor lasers. |
