The spectral functions of URuSi in the hidden-order state are studied by means of ultrahigh-resolution angle-resolved photoemission spectroscopy. High signal-to-noise ratio data uncover the existence of two anomalous fine structures. The structures can be explained by neither ordinary bands nor the development of a hybridization of two states. As a possible origin, we suggest the existence of electron-mode coupling in the ordered state.
