We report a measurement of the neutrino-electron elastic scattering rate of 862 keV Be-7 solar neutrinos based on a 165.4 kt d exposure of KamLAND. The observed rate is 582 +/- 94(kt d)(-1), which corresponds to an 862-keV Be-7 solar neutrino flux of (3.26 +/- 0.52) x 10(9) cm(-2) s(-1), assuming a pure electron-flavor flux. Comparing this flux with the standard solar model prediction and further assuming three-flavor mixing, a.e survival probability of 0.66 +/- 0.15 is determined from the KamLAND data. Utilizing a global three-flavor oscillation analysis, we obtain a total Be-7 solar neutrino flux of (5.82 +/- 1.02) x 10(9) cm(-2) s(-1), which is consistent with the standard solar model predictions.
