A shelf assembly for a refrigerator or freezer includes a receiving plate for receiving objects, a holding arrangement which is joined to the receiving plate to form a structural unit and by means of which the shelf assembly can be mounted in a cooling or freezing space of the refrigerator or freezer on delimiting walls of the cooling or freezing space, and an electrical consumer such as a lighting module. The holding arrangement has a holding element which is arranged in the region of a side edge of the receiving plate, extends along the side edge and is made at least in part of an electrically conducting metal material. The shelf assembly forms a power supply path via the metal material where the power supply path includes an electrically conducting element that extends into a cutout in the holding element and in electrically conducting contact with the holding element.
