Abstract: An electrode structure of a capacitive touch panel including a plurality of receiving electrodes and driving electrodes is provided. Each of the receiving electrodes has at least one opening. Each of the driving electrodes includes a main region and a plurality of elongation regions. The area of each driving electrode is larger than that of each receiving electrode. Parts of the receiving electrodes surround a corresponding one of the driving electrodes, and the elongation regions of the surrounded driving electrode correspondingly stretch into the openings of the receiving electrodes which surround the driving electrode. By using the foregoing electrode structure, the capacitive touch panel is not only capable of providing sensing signals with less noise but is also capable of increasing input signals to enhance the signal to noise ratio.
