Abstract
A high-frequency coil device can maintain a distance between coils at any mounting position in an RF coil including a movable coil unit and can achieve a uniform sensitivity distribution and high sensitivity. A first coil unit configured to move along a substantially circular trajectory and a second coil unit fixed within the substantially circular trajectory are provided, the first coil unit and the second coil unit are disposed at substantially point-symmetric positions, and magnetic coupling between conductor loops provided in both the coil units is maintained substantially constant in a movable range of the first coil unit.
