A component carrier with a first stack and a second stack. The first stack includes at least one first electrically insulating layer structure and at least one first electrically conductive layer structure having a first connection body with a first exposed planar electrically conductive surface. The second stack includes at least one second electrically insulating layer structure and at least one second electrically conductive layer structure having a second connection body with a second exposed planar electrically conductive surface. The first stack and the second stack are connected with each other so that the first exposed planar electrically conductive surface and the second exposed planar electrically conductive surface are connected to establish a vertical two-dimensional electrically conductive connection.
