PURPOSE:To form simply and easily a high-quality plated layer by providing a specified separator between a mask and a plating liquid spray nozzle when a minute part of a material is plated by using the mask with a plating liquid spray method. CONSTITUTION:The region to be plated of a work 11 as a material to be plated is covered with a mask 12A, and a plating liquid spray nozzle 14A and a nozzle holder 16 having a plating liquid discharge hole 15 are provided at the lower stage of a holder 13 of the mask 12A. In addition, a jacket box 19 having a chamber 17 which communicates with a gas-liquid separator 20 and a suction mechanism 21 through a circulation hole 18 is provided thereunder, the plural thin and flat plate-shaped mask bodies 24 of an electrically nonconductive material are provided in parallel in a dent 22 of the mask holder 13. A separator 31A made of an insulating material is further placed in between to separate the region to be plated into plural minute parts to be plated in the specified form.
