Disclosed are a lens actuator and a camera module having the lens actuator. The lens actuator, which includes: a housing; a magnet installed in the housing; a lens holder supporting a lens and installed to ascend and descend in the housing; a spring coupled to the lens holder and supported by the housing to elastically support the lens holder; and a coil coupled to the lens holder in such a way that the coil faces the magnet, a lead line of the coil being interposed between the lens holder and the spring, forms an electric connection structure between the coil and the spring that durable against shocks and humidity, improving the reliability of electric connection, and simplifies the connection structure between the spring and the coil, making it easier to manufacture the lens actuator.
