PROBLEM TO BE SOLVED: To provide an objective lens actuator and an optical pickup having the same for radiating so that heat generating in each coil is not conducted to the object lens, and controlling temperature gradient generating in the object lens.SOLUTION: An objective lens actuator comprises: a first relay part 331 and a second relay part 332 facing across a lens holder; and a cross-linking portion 333 cross-linked between the first relay part 331 and the second relay part 332, where a part of the cross-linking portion 333 is disposed between an objective lens and the lens holder. An optical pickup comprises the objective lens actuator. |
