Abstract
An easily manufacturable multilayer security element has an opaque functional layer that is arranged between two build-up layers of transmissive material. The opaque functional layer has at least one cutout. The layers are connected by lamination to form an areal body with planar surfaces. The cutout is filled up with transmissive material of the build-up layers. One build-up layer supports a feature carrier layer. A security feature, which is arranged at least partially below the cutout, is formed in the feature carrier layer and/or between the functional layer and the feature carrier layer. The cutout forms an inner window through which the security feature is recognizable.
