Zusammenfassung:The present disclosure provides a metal shell of communication equipment. The metal shell of communication equipment includes a metal substrate, a slit penetrating an inner and an outer surface of the metal substrate, a plastic-supporting layer formed on the inner surface of the metal substrate and a decorative layer formed on the outer surface of the metal substrate, wherein a width of the slit on the outer surface of the metal substrate is 15-500 μm, a width of the slit on the inner surface of the metal substrate is 20-600 μm, and a ratio of the width of the slit on the inner surface of the metal substrate to the width of the slit on the outer surface of the metal substrate is between 1.05:1 and 1.5:1.
