An NMR signal acquisition device that can increase the magnetic field homogeneity in a high frequency magnetic field by one of the following. (a) Current paths each having a different inductance are provided to adjust the diversion ratio of the current, (b) A current path branch point is provided in an intermediate part of the winding of a solenoidal coil so that there are more current paths in the intermediate part of the winding than in the current paths connected to the feeding points at both ends, (c) The radiuses of current paths are adjusted, (d) Winding pitches in the axis direction are adjusted, (e) Current path widths are adjusted, and (f) The solenoidal coil has both positive direction current paths and negative direction current paths.
