The invention discloses a base material with a three-dimensional pattern metal effect. The base material comprises a nonmetallic bottom layer and an imitated metal coating which is adhered to one surface of the nonmetallic bottom layer, wherein the imitated metal coating comprises a metal foil layer and a polyethylene glycol terephthalate (PET) layer; the PET layer is adhered to one surface of the metal foil layer through a first adhesive layer; and pattern pits or/and bulges are formed on the other surface of the metal foil layer. The base material has a real three-dimensional pattern effect, and the appearance quality of the base material is improved, so that the base material is applied to different fields.
