The experimental results of the search for the Standard Model Higgs boson with the ATLAS detector at the Large Hadron Collider are reported, based on a dataset of pp collision data with an integrated luminosity of up to 4.9 fb^-1 at sqrt{s}=7 TeV. The search combines several Higgs boson decay channels in a wide range of Higgs boson masses from 110 GeV to 600 GeV. A Standard Model Higgs boson is excluded at the 95% confidence level in the mass ranges from 110.0 GeV to 117.5 GeV, 118.5 GeV to 122.5 GeV, and 129 GeV to 539 GeV, while the range from 120 GeV to 555 GeV is expected to be excluded in the absence of a signal. The most significant excess of events is observed around 126 GeV with a local significance of 2.5sigma. The global probability for such an excess to occur in the full searched mass range is approximately 30%.
