Abstract
In an optical pickup device 3, a supporting base 18 that has a main-shaft bearing 6a with two concentric round holes to pass a main shaft 7 through is formed out of a synthetic resin. On the other hand, an optical base 19, which has a sub-shaft bearing 6b to pass a sub-shaft 8 through and which supports a light emitter 11, a beam splitter 12, a collimator lens 13 and a photodetector 17, is formed by metal die casting process. And a pickup frame 6 is formed by bonding the supporting base 18 and the optical base 19 together with an adhesive.
