Abstract

A tattoo needle structure is provided. A tattoo needle has a plurality of needle tips, an ink holding space is formed by the arrangement of the needle tips, and a multi-component alloy film is deposited on each needle tip of the tattoo needle by sputtering technology, so that when the tattoo needle is dipped into the tattoo ink, the tattoo ink does not stick to the surface of the multi-component alloy film by the hydrophobic property of the multi-component alloy film, and the tattoo ink is contained in the ink holding space by the cohesive property of the tattoo ink. Thus, when the tattoo needle is dipped into the tattoo ink and the tattoo process is performed, the dyeing area of the skin with the tattoo ink is the cross-sectional area of the ink holding space, thereby achieving the technical effect of improving the contouring resolution of a tattoo.
