### Abstract

Let M be a real-analytic CR submanifold of CN and S′ be a realanalytic subset of CN+N′ We say that the pair (M,S′) has the Artin approximation property if for every point p ∈ M and every positive integerℓif H: (CN, p) → CN′ is a formal holomorphic map such that GraphH ∩ (M × CN′ ) ⊂S′, there exists a germ at p of a holomorphic map h^{l} (CN, p) → CN′ which agrees with H at p up to order ^{l}satisfying Graph h ∩ (M × CN′ ) ⊂S′. In this paper, we give some sufficient conditions on a pair (M,S′) to have the Artin approximation property. We show that if the CR orbits of M are all of the same dimension and at most of codimension one in M and if S′ is any partially algebraic subset of CN × CN′ then (M,S′) has the Artin approximation property.
