Camera module

A camera module, comprising an image sensor, a lens and an OIS (Optical Image Stabilization) unit, the OIS unit including,

• a housing unit including a first housing and a second housing arranged at an upper surface of the first housing and centrally formed with an opening,
• a holder module including an outer blade spaced apart from an inner floor surface of the first housing at a predetermined distance, and a bobbin arranged at an inner surface of the outer blade,
• a spring member arranged at the outer blade to support a movement of the bobbin to an optical axis,
• an autofocus driving unit including an autofocus coil arranged at a periphery of the bobbin, and a magnet that interacts with the autofocus coil,
• an OIS driving unit including a magnet and an OIS coil, the magnet and the OIS coil arranged on the housing unit and the holder module,
• a plurality of wires that support a movement of the holder module to a direction perpendicular to the optical axis by the OIS driving unit while being spaced apart from the first housing at a predetermined distance, and electrically connected to the autofocus coil through the spring member configured to provide a current to the autofocus coil,
• a buffering unit integrally formed at a partial section of each the wires of the plurality of wires and arranged with an adhesive material, and
• a first PCB (Printed Circuit Board) configured to apply a current to the autofocus coil and the OIS coil,
• wherein the lens is coupled to the bobbin, and
• wherein the camera module further comprises a second PCB, and the image sensor is arranged on the second PCB.
