A heat exchanger, in particular for a motor vehicle, comprises a collector box and at least one longitudinal row of multi-channel flat tubes through which a first fluid can flow. The collector box is made up of stacked plates including: a header plate with at least one row of mounting slots receiving an end portion of each tube, a distribution plate comprising at least one row of distribution slots, a cover plate comprising at least one row of collecting apertures which connect at least some of the distribution slots to a manifold, at least one collecting aperture being arranged between two adjacent distribution slots. Said collecting aperture is arranged in a main recess provided in the bottom face of the cover plate.
