PROBLEM TO BE SOLVED: To fix a mirror member without adhesive by providing a thin part on a slide base, cutting a part of the thin part down, forming a pressing piece and fixing the mirror member with the pressing piece. SOLUTION: This device is an optical pickup device provided with a slide base 13 accessibly/separably supported for an optical disk D and a prism mirror 16 fitted to the slide base 13, bending an optical axis of a laser beam emitted from a light source and irradiating it on the optical disk D, and records and/or reproduces an information signal on the optical disk D. The slide base 13 is provided with a mirror housing hole 22 housing the prism mirror 16, tilted projected stripes 23 provided in the mirror housing hole 22 for supporting the reflection surface 16a side of the laser beam of the prism mirror 16 and thin forming holes 25 provided on the peripheral edge part of the mirror housing hole 22 and forming the thin parts 24 between with the mirror housing hole 16, and thin parts 24 are cut down, and pressing pieces 26 are formed, and the prism mirror 16 is fixed with the pressing pieces 26. |
