A voice coil motor is provided to prevent the coil from being bent by connecting the spring connected to the bobbin bottom to the end of the coil by soldering. The voice coil motor comprises the bobbin(210), and permanent magnet, and coil and spring. The coil is wound outside the bobbin movable to vertical direction. The wire-wound coil forms the magnetic field according to the size and direction of the current. The coil moves the bobbin fixing the lens to the vertical direction by attraction and repulsive force of the adjacent permanent magnet. In the bottom of bobbin, the spring for elastically supporting the vertical displacement of bobbin is connected. The start line of the coil and the end line(250) are connected with the end part of the spring(230) by soldering.
