Description
We present the form factor of pion using overlap fermion. We work on 2+1 flavor domain-wall configurations on $24^3\times 64$ lattice with lattice spacing $a=0.083 \, {\rm{fm}}$ and $32^3 \times 64$ lattice with lattice spacing $a=0.083 \, {\rm{fm}}$ genterated by RBC/UKQCD collaboration. With multi--mass algorithm, we do an extrapolatiion of finite lattice spacing and varies valence quark masses to form factor at pysical pion with a range of space-like $Q^2$ from 0.0 to 0.6 ${\rm{GeV^2}}$.
