A touch panel includes a substrate, a first and a second patterned conductive layers respectively disposed on an upper surface of the substrate and a lower surface opposite to the upper surface. The substrate has a first sensing area and a first circuit bonding area located on the upper surface. The first patterned conductive layer includes a plurality of first sensing series and a plurality of first dummy patterns respectively located in the first sensing area and the first circuit bonding area. Each of the first sensing series is electrically insulated from each other and has a first terminal extending into the first circuit bonding area. The first dummy patterns surround each first terminal and are electrically insulated from each first terminal. A plurality of first dummy patterns intervenes between any two adjacent first terminals in the first circuit bonding area.
