An NMR probe having a high-sensitivity solenoid probe coil for receiving free induction decay (FID) signals in nuclear magnetic resonance (NMR) spectroscopy, and an NMR spectrometer which incorporates this probe. The solenoid probe coil is fabricated by a building block approach where it mainly consists of coil substrates having superconducting thin film coils made from superconducting thin film thereon, and side holding plates and a wiring substrate with line pattern of superconducting thin films which are both perpendicular to the coil substrates. The superconducting thin film coils are connected with the line patterns of superconducting thin films by capacitive coupling to make the solenoid coil configuration and solenoid probe coil of superconducting material.
