| 发明名称 | Camera module and titanium-copper foil | ||
| 摘要 | A camera module (1) which includes a lens (3); a spring member (9a, 9b) which elastically urges the lens (3) toward an initial position along an optical axis direction; an electromagnetic drive means (11) capable of driving the lens (3) along the optical axis direction by producing an electromagnetic force against an urging force of the spring member (9a, 9b); and a control means (12) configured to control a drive current supplied to the electromagnetic drive means (11), wherein the spring member (pa, 9b) contains 2.9% to 3.5% by mass of Ti, with the balance being copper and inevitable impurities, and has a Vickers hardness equal to or greater than 350. | ||
