    摘要: A touch structure, a method of manufacturing same, a touch device, and a method for determining a touch position are provided. The touch structure includes a first touch unit (1) and the first trace (13). The first touch unit (1) includes a first touch electrode (11) and a second touch electrode (12) that are adjacent to each other and insulated from each other. The first touch electrode (11) and the second touch electrode (12) are both self-capacitance electrodes and both have a thin end (11A, 12A) and a thick end (11B, 12B) that are arranged opposite to each other. The first trace (13) includes a first sub-trace (131) and a second sub-trace (132). The first sub-trace (131) is coupled to the first touch electrode (11) and the second sub-trace (132) is coupled to the second touch electrode (12). The touch structure is able to realize multi-point touch.
