We investigate incommensurate magnetic fluctuations in Sr2RuO4 by inelastic neutron scattering using the chopper spectrometer AMATERAS. Below Tc, we found the spin resonance at Q = (0.3, 0.3, 0.5) with energy of the superconducting gap 2Δ. This result strongly indicates that the superconducting gap of Sr2RuO4 has horizontal line nodes.
