An optical pickup actuator is provided to adjust skew of an objective lens easily and reliably by preventing the objective lens from shaking after adjusted. An optical pickup actuator comprises an objective lens(11,12) and a lens holder. The objective lens collects a laser beam on a recorded layer of an optical disc. The lens holder includes a main holder(14) and a sub holder(15). The main holder is formed with a groove at the upper part, where an inner surface(16) of the groove is inclined downward. The sub holder is mounted with the objective lens and has a curved bottom to be contacted with the inner surface of the groove of the main holder.
