A beam size monitor so called Shintake monitor, which uses the inverse Compton scattering between the laser interference fringe and the electron beam was designed for and installed at ATF2. The commissioning at ATF2 was started in the end of 2008 and succeeded in the measurement of the fringe pattern from the scattered gamma-rays. The present status of the Shintake monitor is described here.
