A volume coil for a magnetic resonance imaging system is composed of a number of coil units. In the coil, there are overlapped parts between two adjacent ones of the coil units for eliminating coupling between these two adjacent coil units. Two next-adjacent ones of the coil units, which are separated from each other by one coil unit, are each provided with an inductor, and these two inductors are coupled with each other for eliminating coupling between these two next-adjacent coil units. All coil units are collected on one axial end face of the coil. Two coil units in the coil that are neither adjacent coil units nor next-adjacent coil units are connected with each other on the end face by a capacitance circuit or a inductance circuit for eliminating the coupling between these two coil units that are neither adjacent coil units nor next-adjacent coil units. The coupling among the various coil units is relatively thoroughly eliminated, and the signal-to-noise ratio of the signal received by the coil is increased.
