A voice coil motor camera using a Halbach array is provided to improve a focusing accuracy between an imaging sensor and an objective lens by using a magnetic using a Halbach array. A camera includes a voice coil motor, a coil(300), a magnet(200), and a yoke(100). The coil is arranged in the voice coil motor. The magnet moves the coil. The yoke is attached to an exterior of the magnet. The coil is arranged to be opposite to the magnet, so that an electromagnetic force is generated. The coil is moved back and forth according to a direction of a current. The magnets are aligned in a Halbach array having different magnetization directions.
