In this paper, the authors shed new light on the large-order behavior of the perturbation theory for the quantum mechanics with degenerate minima. The dominant contribution at large-order of perturbation is identified as a bounce-like solution of an effective theory in Euclidean path-integral formalism. Based on this observation, the authors define an improved perturbation theory, which utilizes the symmetry of the theory. It is shown to yield a Borel-summable series.
