Abstract
Disclosed is a capacitive touch panel having a circuitous conductor pattern structure. The capacitive touch panel contains a number of first axial conductor assemblies and a number of second axial conductor assemblies, wherein each second axial conductor assembly includes a number of second axial conductor cells which are composed of a number of bar shape figures with accordion shape or wave shape edges. Electrical fields and induced capacitors are generated between adjacent axial conductor assemblies with different directions when giving control signals. Then the touched position is detected. Circuitous conductor pattern increases the region of the first axial conductor assembly and the inducing range of electrical field, thus the amount of the axial conductor assemblies and conduction lines can be reduced.
