Abstract
An attachment portion 20 for a laser diode 1 is formed on a frame 2 of an optical pickup device. The attachment portion 20 includes a pair of inner peripheral faces 233 and 234 to which an outer peripheral face 103 of a circular stem 101 of the laser diode 1 can be press-fitted, and a pair of convex faces 241 and 242 rockably supporting an annular end face 104 of the stem 101 around a rocking center line L1. When the laser diode 1 is press-fitted and is then rocked around the rocking center line L1, the intensity distribution center of a laser beam 11 emitted from the laser diode 1 can be coincident with an optical axis L of an optical system.
