An RF coil has an improved structure to prevent an excessive heat from being transferred to an object, and a magnetic resonance imaging apparatus includes the same. The MRI apparatus includes an RF coil configured to receive an RF signal, wherein the RF coil may include a first cover configured to allow thermal insulation material to be injected into the inside thereof, a second cover configured to allow thermal insulation material to be injected into the inside thereof and detachably coupled to the first cover to form an inner space with the first cover, and at least one circuit board disposed in the inner space and on which a circuit element configured to receive the RF signal is mounted.
