  Three dimensional supersymmetric gauge theories are often in a gapped phase,
in which SUSY is spontaneously broken, if all the matter fields are massive and
decoupled in the low energy. We study this phase in the large $N$ limit using
the localization technique for the theory on the ellipsoid, which interpolates
the round three sphere and the flat space compactified on $S^1$. We find a
large $N$ saddle point solution for the gauge theory with some massive matter
fields. This solution gives a vanishing (generalized) Polyakov loop in the flat
space limit, thus, it corresponds to the confining phase at the leading order
in the $1/N$ expansion.
