Zusammenfassung:PROBLEM TO BE SOLVED: To effectively execute decoupling with a small RF coil in an MRI (Magnetic Resonance Imaging) device including a vacuum container for suppressing noise associated with application of gradient magnetic field. SOLUTION: The nuclear magnetic resonance imaging device includes a high-frequency coil 4 which applies an exciting magnetic field to a subject P disposed in a magnetostatic space; and a gradient magnetic field application means 5 which applies a gradient magnetic field to the subject P. The nuclear magnetic resonance imaging device further includes a vacuum container in which the gradient magnetic field application means 5, the high-frequency coil 4, and a shielding means 4a installed between the high-frequency oil 4 and the gradient magnetic field application means 5 are disposed.
