Abstract
A touch electrode structure and a manufacture method thereof, a touch panel, and an electronic device are provided. The touch electrode structure includes a first touch electrode and a second touch electrode intersecting with each other to form a mutual capacitance for touch detection; the first touch electrode is longer than the second touch electrode; the first touch electrode includes a first hollow region, the second touch electrode includes a second hollow region, and a hollow area of the first touch electrode is greater than that of the second touch electrode; and the touch electrode structure further includes at least one first dummy electrode, which is within the first hollow region and is arranged in a same layer as at least part of the first touch electrode, and they are insulated from each other.
