In heavy-fermion compound URuSi, unconventional superconductivity appears in the so-called "hidden order" (HO) state with a superconducting (SC) transition temperature of 
= 1.4 K. In the H
state, long-range electronic order is well established below 
= 18 K, but the order parameter has so far been undetectable, and hence has not yet been identified. It is an intriguing subject to clarify the mechanism of superconductivity in the HO state. We have performed Si 
measurements using a high-quality single crystal of URuSi. The extremely narrow NMR spectra obtained for the single crystal allowed us to achieve much higher experimental resolution. We will discuss the possible SC pairing state from our measurement.
