We discuss the non-perturbative aspect of zero dimensional superstring. The perturbative expansions of correlation functions diverge as ∑l(3l)!κ2l, where κ is a string coupling constant. This implies there are non-perturbative contributions of order \e^Cκ^-2 \over 3. (Here C is a constant.) This situation contrasts with those of critical or non-critical bosonic strings, where the perturbative expansions diverge as ∑ll!κ2l and non-perturbative behaviors go as \e^Cκ-1. It is explained how such nonperturbative effects of order \e^Cκ^-2 \over 3 appear in zero dimensional superstring theory. Due to these non-perturbative effects, the supersymmetry in target space breaks down spontaneously.
