PROBLEM TO BE SOLVED: To provide a faucet to which matting processing with good appearance, is performed.SOLUTION: A coating film 15 is formed on a surface of a faucet. A surface of the coating film 15 is subjected to matting processing by wet blasting. Since in the wet blasting processing, projected grains having fine grain diameter can be obtained different from in a dry blasting processing, so that, the mat surface with good touch feeling and fineness, can be acquired. In addition, the blasting flow is wet, so that such a situation in which, a coating film surface is overheated due to collision of the projected grains, or oxidized, or affected by impurities, can be suppressed, and color change of the coating film surface can be prevented. In addition, the projected grains having small grain diameter and mass, are used, so that the projected grains hardly bite into the coating film surface, and even biting, the biting grains are flushed by the blasting liquid, so that the coating film surface with good touch feeling can be acquired.SELECTED DRAWING: Figure 1 |
