Solenoid coil arrangements for sending a high-frequency wave, receiving or sending and receiving in a measurement of an NMR signal, wherein the solenoid coil has at least two leader lines for connections to a resonance circuit. A static magnetic field compensating member is arranged outside of the leader lines and is at least one of: (a) arranged to extend a main solenoid coil in an axial direction, and not to generate a high-frequency magnetic field in a direction to cancel a high-frequency magnetic field generated by the main solenoid coil; (b) constituted by an insulant having a magnetic susceptibility of the same sign as a material of a main solenoid coil and is in an outer side in an axial direction of the main solenoid to contact with the main solenoid coil; and (c) constituted by ring-shaped members divided into a plurality of sections in a circumferential direction.
