In this work, we present a forecast of He II reionization detection using the DM and redshift measurements of FRBs from the upcoming Square Kilometre Array (SKA). Assuming a model of the Universe in which He II reionization occurred at a specific redshift $z_{\\rm re}$, we analyze what extent the signal-to-noise ratio ($\\mathrm{S/N}$) for the detection of the amplitude of reionization can be achieved in the era of SKA.
