PROBLEM TO BE SOLVED: To improve frequency characteristics for an optical pickup by strengthening a rigidity of a rising piece without making a metal plate thicker when the rising piece for attaching a magnet is formed by bending the metal plate for an actuator of the optical pickup. SOLUTION: Rising pieces 23, 23 are molded by bending on a base component 2 for holding a lens holder 1 with an objective lens 13 to be displaced toward both a focusing direction and a tracking direction. Strength for the base component 2 is enhanced by broadening width to other positions for a molded by bending part 32 for a foot 31 for the rising pieces 23, 23. It is desirable for a side view shape for the rising piece 23 to be made a trapezoid. COPYRIGHT: (C)2004,JPO
