A study was performed on Kamioka long-baseline neutrino oscillation experiment (K2K). The indications of neutrino oscillation such as a reduction of flux together with a distortion of the energy spectrum were observed in the experiment. In Super Kamiokande (SK), 250 km from the neutrino production point, fifty-six beam neutrino events were observed. It was found that the probability that the measurements at SK is explained by statistical fluctuation without neutrino oscillation is less than 1%.
