PROBLEM TO BE SOLVED: To provide an RF (radio frequency) coil having stable characteristics which can prevent circuit elements on the coil from being damaged by reducing an electric potential difference between adjacent coils in the RF coil of multiple channels being constituted by using single loop coil elements, and a magnetic resonance imaging device using the RF coil. SOLUTION: This RF coil is constituted of four single loop coil elements 101 to 104 which form an approximately cylindrical shape. In the RF coil, two adjacent coil elements form a pair, and the two coil elements of each pair are connected by a common ground electric potential at the adjacent part. In a vicinity of the common ground electric potential, a signal outputting unit for an RF exciting signal is provided, and the RF exciting signal received by the coil elements is outputted through the signal outputting unit. Therefore, a voltage difference between adjacent coil elements is reduced, and circuit elements can be prevented from being damaged. COPYRIGHT: (C)2004,JPO
