Abstract

In this paper, we use the type Ia supernova data to constrain the model of holographic dark energy. For , the best fit result is , the equation of the state of the holographic dark energy $w^0_\d = -0.91$ and the transition between the decelerating expansion and the accelerating expansion happened when the cosmological red-shift was . If we set as a free parameter, the best fit results are , , $w_\d^0=-2.67$, which sounds like a phantom today, and the transition redshift is .
