  In this paper we prove an infinite-dimensional version of Sard's theorem for
Fr\'{e}chet manifolds.
  Let $ M $ and $ N $ be bounded Fr\'{e}chet manifolds such that the topologies
of their model Fr\'{e}chet spaces are defined by metrics with absolutely convex
balls.
  Let $ f: M \rightarrow N $ be an $ MC^k$-Lipschitz-Fredholm map with $ k >
\max \lbrace {\Ind f,0} \rbrace $. Then the set of regular values of $ f $ is
residual in $ N $.
