Abstract:
1. A solenoid coil for an NMR signal used for sending a high-frequency wave, receiving or sending and receiving in a measurement of an NMR signal, wherein the solenoid coil comprising: a main solenoid coil and a static magnetic field compensating member which is arranged on the both ends of the main solenoid coil to form one combination structure is at least one of: (a) arranged to extend said main solenoid coil in an axial direction, and not to generate a high-frequency magnetic field in a direction as to cancel a high-frequency magnetic field generated by said main solenoid coil; and (b) constituted by an insulant having a magnetic susceptibility of the same sign as a material of a main solenoid coil and is arranged in an outer side in an axial direction of the main solenoid to contact with said main solenoid coil.
