Abstract: The present disclosure relates to an electronic device. The electronic device includes a circuit board. The circuit board includes a wiring layer and a patterned electrode layer. The wiring layer includes a plurality of wires. One of the wires includes a trace part and a terminal part connected to the trace part. The patterned electrode layer is disposed opposite to the wiring layer. The trace part and the patterned electrode layer have a first overlapping area, the terminal part and the patterned electrode layer have a second overlapping area, and a ratio of the first overlapping area to the second overlapping area is between 0.7 and 1.3.
