Nous étudions le courant résiduel de type Bochner-Martinelli $R^f$ associé à un $m$-uple de germes de fonctions holomorphes $f=(f_1,\cdots ,f_m)$ définies à l’origine $0\in {\mathbf{C}}^n$ dont l’ensemble des zéros communs se réduit à $0$. Nos résultats principaux sont : une description géométrique de $R^f$ en terme des valuations de Rees associées à l’idéal $\left(f\right)$ engendré par f et la caractérisation du cas où l’idéal annihilateur de $R^f$ est égal à $\left(f\right)$.

We study the residue current $R^f$ of Bochner-Martinelli type associated with a tuple $f=(f_1,\cdots ,f_m)$ of holomorphic germs at $0\in {\mathbf{C}}^n$, whose common zero set equals the origin. Our main results are a geometric description of $R^f$ in terms of the Rees valuations associated with the ideal $\left(f\right)$ generated by $f$ and a characterization of when the annihilator ideal of $R^f$ equals $\left(f\right)$.
