PROBLEM TO BE SOLVED: To provide a camera motor that is simple in configuration, has the ability to adjust many focal points and is low in cost. SOLUTION: The camera motor includes: at least two lens modules; permanent magnets surrounding the circumferential faces of the corresponding lens modules; upper and lower coils bases set at both ends of each of the permanent magnets; and upper coils and lower coils wound around the upper coil bases and lower coil bases respectively. When power is supplied to the upper and the lower coils, the lens modules are moved between different focal points by a magnetic field generated in the upper and the lower coils and by the acting forces of the permanent magnets.
