An assembly carrier for installation into a motor vehicle includes a large-area carrier body molded at least partially from fiber-reinforced plastic, fastening points, which are provided on the carrier body, for fastening functional components of a motor vehicle to the carrier body, and a gate mark which projects from the carrier body and which represents a section of the path along which the molding compound for molding the assembly carrier was conducted into a cavity, which forms the carrier body, of a molding die. The gate mark has at least one longitudinally extended gate section which is curved in cross section through the carrier body and the gate mark and whose longitudinal sides which are situated opposite, and which face away from, one another run in each case along a curved path and merge in each case along the respective path into the carrier body.
