Abstract
Provided is an MRI device, which has a structure for cooling a heat spot efficiently and which has an inclined magnetic field coil (2) of high reliability. At least one of X, Y and Z coils of the inclined magnetic field coil (2) is a coil (103) also acting as a cooling pipe, which has a hollow region for causing a cooling medium to flow therein. In the coil (103) acting as the cooling pipe, there are fixed heat-conductive members (201 and 202). Of these, the heat-conductive members (201) are arranged at positions overlapping the regions, at which the density of another coil pattern is the highest. The heat-conductive members (202) are arranged at positions overlapping the regions around through holes (301) at least partially.
