Assume that $M$ does not contain any complex-analytic hypersurface of $\C^N$ and that there exists at least one strongly pseudoconvex point on $M$. We show that any CR map $f\colon M\to §$ of class $C^{N'-N+1}$ extends holomorphically to a neighborhood of $M$ in $\C^N$.11 pagesComplex Variables32H02, 32H04, 32V20text
