  We consider finite volume effects on the electro-magnetic pion form factor
near the chiral limit, in the so-called $\epsilon$ regime. The
pseudoscalar-vector-pseudoscalar three-point function is calculated in the
$\epsilon$ expansion of chiral perturbation theory to the next-to-leading
order. In the $\epsilon$ regime, finite volume effects are non-perturbatively
large in general. However, we find a way to remove its dominant part, by
inserting momenta to the correlators, and taking an appropriate ratio of them.
The subleading contribution is, then, shown to be perturbatively small, and one
can extract the form factor as in a similar way to that in the $p$ regime.
