Claim 12:
13. A manufacturing method of a touch panel, comprising steps of:
sequentially forming a metal layer and a blackening layer on a base layer in a multi-chamber;
patterning the metal layer and the blackening layer in a mesh pattern;
etching the metal layer and the blackening layer to form a metal mesh electrode with the blackening layer laminated,
wherein the blackening layer has the same width as a top width of the metal mesh electrode, and
wherein a side surface of the metal mesh electrode has a positive tapered shape in which a bottom width is larger than a top width, and a taper inclination angle is 80° or more and less than 90° with respect to the base layer.
