A low-gloss metal plate includes a metal body and a plurality of metal pattern units. The metal body has a first surface and a second surface opposite to each other. The plurality of metal pattern units protrude from the first surface and are arranged to form a regular pattern. One of the plurality of metal pattern units has a top, a base and a sidewall. The base at least partially overlaps with the first surface. The sidewall connects the top with the base and forms an angle less than 60° with the base.
