PROBLEM TO BE SOLVED: To obtain a solenoid coil capable of generating a high-frequency magnetic field, having high magnetic field homogeneity, and a nuclear magnetic resonance signal acquisition device having a probe mounted with the coil. SOLUTION: (a) Current paths having different inductances are provided, and their current partition ratios are adjusted. (b) By providing a current path junction in the middle of the winding of the solenoid coil, the number of current paths in the middle of the winding is made larger than that of current paths connected to each feed point at both ends. (c) The current path radii are adjusted. (d) The current path gaps are adjusted. (e) The current path widths are adjusted. (f) The solenoid coil is made to have both a forward current path and a backward current path. By equipping with any one of these, the magnetic field homogeneity of the high-frequency magnetic field can be improved. COPYRIGHT: (C)2007,JPO&INPIT
