The deficit of the solar neutrino event rate (so called "solar neutrino problem") was initially presented by Davis since 1960s. It was established as a deficit of the solar neutrino flux by Kamiokande led by Koshiba. In the recent two years, it was found that the solar neutrino problem is due to neutrino oscillations by the results from Super-Kamiokande and SNO experiments. Combining with other solar neutrino experiments, most probable solution of the neutrino oscillation parameters was the Large Mixing Angle (LMA) solution. In December 2002, the reactor long baseline experiment. KamLAND, confirmed that the LMA is the correct solution.
