PURPOSE:To improve the workability in masking and unmasking and to uniformize the quality of a product by masking the part not to be coated with a masking member formed with a plate material of specified shape. CONSTITUTION:The parts 11-13 to be coated and the parts 14 and 15 not to be coated are arranged alternately, crisscross, and successively to form component members 1 and 2, and only the parts 11-13 are coated. The parts not to be coated are masked with the masking members 21 and 41 forming a plate when developed, wrapping the parts not to be coated when folded, and capable of parting the part to be coated and the part not to be coated with its peripheral edge part, and the part to be coated is coated. As a result, the workability in masking and unmasking is improved, and the quality of the product can be uniformized.
