1. A magnetic resonance imaging apparatus comprising:

  • a magnet which generates a magnetostatic field and forms a magnetostatic field; and

    an RF coil which performs at least one of transmission of a high-frequency signal to the magnetostatic field and reception of a nuclear magnetic resonance signal generated from a subject placed inside the magnetostatic field,wherein the RF coil includesa sheet-like conductor, andan antenna unit,the antenna unit includesa rung conductor which is arranged at a predetermined distance from the sheet-like conductor, andtwo electric field conductors which are arranged in both end portions of the rung conductor at a predetermined distance from the sheet-like conductor, andthe rung conductor and the sheet-like conductor configure a loop circuit which resonates at the frequency of the high-frequency signal transmitted from the RF coil or the nuclear magnetic resonance signal received by the RF coil.
