This article is a survey on the theory of Lelong numbers, viewed as a tool for studying intersection theory by complex differential geometry. The paper contains earlier works of the author [Mém. Soc. Math. Fr., Nouv. Sér. 19, 124 p. (1985;

Zbl 0579.32012) and Acta Math. 159, 153- 169 (1987;

Zbl 0629.32011)] and of

*Y. T. Siu* [Invent. Math. 27, 53- 156 (1974;

Zbl 0289.32003)]. Many results are given with complete proofs, which are shorter and simpler than the original ones. The references contain 37 items on these topics.
