  The latest results of the K2K experiment are reported. The results are based
on data taken from June, 1999, to June, 2000, corresponding to a total $2.6
\cdot 10^{19}$ protons on target. Twenty seven fully-contained events in the
22.5 kton fiducial volume of Super-Kamiokande (SK) are observed. The expected
number of events is estimated to be 40.3^{+4.7}_{-4.6} assuming the null
oscillations hypothesis.
