The sensitivity of the ATLAS experiment to low mass SM Higgs produced via Vector Boson Fusion mechanism with $Hto gammagamma$ is invest igated. A cut based event selection has been chosen to optimize the expected signal significance with this decay mode. A signal significance of 2. 2$ sigma$ may be achieved for $M_H=130 gev$ with 30 fb$^{-1}$ of accumulated luminosity.
