For the purpose of providing an RF coil that enables satisfactory imaging of the prostate, the RF coil is composed of a first saddle coil and a second saddle coil. The first saddle coil has two loop portions opposed to each other so that they can sandwich the inferior abdomen of a human body antero-posteriorly. The second saddle coil has two loop portions opposed to each other so that they will permit insertion of the inferior limbs of a human body thereinto and can sandwich the inferior abdomen thereof laterally.
