The invention discloses a porous array polymethyl methacrylate template and a preparation method thereof. The template has good solubility and is applicable to preparation of a demoulded metal micro-nanowire array material. According to the preparation method, first-level hot stretch is carried out on a preform rod composed of polymethyl methacrylate and polystyrene in a wire drawing device; close packing fixing is carried out on a prepared first-level composite filament; second-level hot stretch is carried; third-level hot stretch is carried out after close packing fixing is carried out on the prepared second-level composite filament; and slicing and dissolution are carried out on the composite filament. According to the preparation method, required devices are simple, raw materials are easy to get, the production cost is low, the environmental pollution is little, the repeatability is high, the method is applicable to continuous mass production, the pore diameter, pore spacing and pore depth of the porous a
