We show that the standard model Higgs field can realize the quadratic chaoticinflation, if the kinetic term is significantly modified at large field values.This is a simple realization of the so-called running kinetic inflation. Thepoint is that the Higgs field respects an approximate shift symmetry at highenergy scale. The tensor-to-scalar ratio is predicted to be $r \simeq 0.13 -0.16$, which nicely explains the primordial B-mode polarization,$r=0.20^{+0.07}_{-0.05}$, recently discovered by the BICEP2 experiment. Inparticular, allowing small modulations induced by the shift symmetry breaking,the negative running spectral index can also be induced. The reheatingtemperature is expected to be so high that successful thermal leptogenesis ispossible. The suppressed quartic coupling of the Higgs field at high energyscales may be related to the Higgs chaotic inflation.
