Abstract
A touch sensor includes a substrate, sensing channels, and a protective layer. The sensing channels are disposed at intervals on a surface of the substrate, and any one of the sensing channels includes an electrode portion and a silver trace portion electrically connected to the electrode portion. The protective layer is disposed on the substrate and covers and encapsulates the sensing channels. After the touch sensor is subjected to a salt spray test with sodium chloride solution of a mass percentage concentration of 5% at a rate of 1 mL/H to 2 mL/H under an ambient temperature of 35° C. for 48 hours, a resistance change rate of any one of the sensing channels is less than or equal to 10%, and a resistance distribution difference between the sensing channels is less than or equal to 10%.
