PROBLEM TO BE SOLVED: To reduce production of an unnecessary artifact. SOLUTION: An RF coil element, which generally forms a cylindrical structure and includes a plurality of conductive members (36) at intervals so as to prescribe an imaging volume, receives an RF signal and impresses a magnetic field to the imaging volume. A power divider (44) is adapted so that an RF signal generated by a signal generator (42) can be distributed, as signals equal in power, to the respective conductive members (36). Divided signals from the power divider (44) are received by a phase shifter (46); each of the divided RF signals is phase-shifted uniformly in each of the conductive members (36) by the phase shifter (46); and each conductor carries the signal at a different phase angle to each of the other conductors. An amplifier (38) for independently controlling a current amplitude of the signal carried on each of the conductors is coupled to each of the conductive members (36).
