We report the experimental observation of a magnetic-field-tuned superconductor-insulator transition (SIT) in ultrathin TiN films. The low temperature transport properties of these films show scaling behavior consistent with a transition driven by quantum phase fluctuations in two-dimensional superconductor. The magnetoresistance reveals peak and a subsequent decrease in fields higher than the critical field. The temperature dependences of the isomagnetic resistance data on the high-field side of the SIT have been analyzed and the transition from insulating to metallic phase is found, with at high fields the zero-temperature asymptotic value of the resistance being equal to h/e2.
