1. An RF coil resonating at a first resonance frequency and a second resonance frequency respectively corresponding to a first element and a second element being different in magnetic resonance frequency, comprising at least one conductor loop,wherein the conductor loop has a parallel circuit including a first branch comprising a first capacitor and a second branch comprising a third capacitor and a first parallel resonance circuit configured by a second capacitor and a first inductor;

  • the first capacitor has capacity to cause the RF coil to resonate at signal transmission and reception of the first resonance frequency when the first resonance frequency is higher than the second resonance frequency;

    product of a value of the second capacitor and a value of the first inductor is determined as a value thereof based on the first resonance frequency; and

    the third capacitor has such capacity that a resonance frequency for a series circuit configured by the first parallel resonance circuit and the third capacitor gets higher than the second resonance frequency at the time of transmission and reception of a second resonance frequency signal.
