Wepresent measurements of nu_µ disappearance in K2K, the KEK toKamioka long-baseline neutrino oscillation experiment. One-hundred and twelve beam-originated neutrinoevents are observed in the fiducial volume of Super-Kamiokande withan expectation of 158.1_-8.6^+9.2 events without oscillation. A distortion ofthe energy spectrum is also seen in 58 single-ring muonlikeevents with reconstructed energies. The probability that the observations areexplained by the expectation for no neutrino oscillation is 0.0015%(4.3sigma). In a two-flavor oscillation scenario, the allowed Deltam² regionat sin²2theta=1 is between 1.9 and 3.5×10^-3 eV² at the 90%C.L. with a best-fit value of 2.8×10^-3 eV².
