The invention relates to a longitudinal beam (1) for a road vehicle, comprising: a plurality of interior elements (2-6), which, in the cross-section of the longitudinal beam (1), run in a first direction (Y) and are arranged at an offset to one another in a second direction (Z); and at least one planar exterior element (10), which runs in the second direction (Z), wherein at least two interior elements (2-6) are connected to one another at both ends with respect to the first direction (Y) by means of at least one exterior element (10) such that at least one chamber (11) is formed therebetween (10). The aim of the invention is to provide a longitudinal beam that is optimized with respect to both weight and mechanical properties and that is economical to produce. This aim is achieved, according to the invention, in that at least one interior element (2-6) is designed as a sheet metal part having a web (2.1, 3.1, 4.1) running in the first direction, from which web flanges (2.2, 3.2, 4.2) protrude at at least one end of said web, which flanges are produced by the shaping splitting of sheet metal and at least one of which flanges is connected to an exterior element (10).
