Let (M,F) be a forward complete and connected Finsler manifold of dimensional n ≥2 . In this study, we extend Wan’s extension theorem in Riemannian manifolds to Finsler manifolds by using the weighted Ricci curvature Ric_N bounded below. The proof of theorem is obtained by the Laplacian comparison theorem on Finsler manifolds and the excess function.
