A touch panel including a substrate, a first patterned conductive layer, a second patterned conductive layer and a circuit board is provided. The substrate has a first surface, a second surface, a first bonding area and a second bonding area. The first patterned conductive layer disposed on the first surface includes first sensing series electrically insulated from each other. The second patterned conductive layer disposed on the second surface includes second sensing series electrically insulated from each other. The circuit board includes a rigid portion, a first flexible bonding portion and a second flexible bonding portion. The first flexible bonding portion and the second flexible bonding portion are electrically connected to the rigid portion. The first flexible bonding portion is electrically connected to the first sensing series in the first bonding area. The second flexible bonding portion is electrically connected to the second sensing series in the second bonding area.
