Provided is an RF coil which can highly efficiently and uniformly
irradiate a RF magnetic field having two or more magnetic resonance
frequencies close to each other, and receive magnetic resonance signals
of two or more magnetic resonance frequencies close to each other with
high sensitivity and uniform sensitivity profile in an MRI apparatus. Two
or more frequencies to which the coil is tuned are adjusted so as to be
between resonance frequencies of series resonant circuits constituting
the RF coil.
