Abstract
A lens drive unit that offers enhanced reliability in connection between an actuator electrode and an electric wire is provided. In the lens drive unit, an actuator has a weight housed in an holding portion of a base member and is thereby fixed in the base member. Electrodes on a lateral surface of the weight directly contact respective terminal electrodes on an inner lateral surface of the holding portion, so that an electrical connection is established therebetween. The arrangement enhances reliability in connection between the actuator electrodes and the terminal electrodes.
