Abstract
Provided is an optical pickup actuator including a blade, a plurality of wires, coils, magnets, and connectors. The blade has an objective lens. The plurality of wires support the blade so that the blade moves around a predetermined holder. The coils are installed on the blade. The magnets interact with a current flowing through the coils to generate an electromagnetic force. The connectors electrically connect the wires and the coils so that a power supply supplies a current to the coils via the wires. The connectors include conductive plating terminals that are connected to the coils and installed on the body of the blade so that ends of the wires are connected to the connectors.
