| 1. An RF coil for an MRI apparatus comprising:
an 8-shaped coil having a figure-8 configuration through which a conductive path crosses; and
an impedance adjustment coil that connects crossing points of the conductive path,
wherein the crossing points of the conductive path are connected in parallel through the impedance adjustment coil that is
connected in parallel with a floating capacitance between the crossing points of the conductive path, and in a Larmor frequency
that is in proportion to the intensity of a magnetostatic field, an impedance between the crossing points of the conductive
path is increased and a current that flows between the crossing points of the conductive path is reduced.
