Scalar field theory with an asymmetric potential is studied for φ^4 theory with φ^3 symmetry breaking. The equations of motion are solved analytically up to the second order to get the bounce-solution. The bounce action and the critical radius of the bubble are obtained beyond the thin-wall approximation. Our analytical results are consistent with those of the thin-wall approximation.
