A stylus including a shaft, an elastic cover, a tip base and an elastic element is provided. The shaft includes a groove and an end portion. The groove connects to the end portion. The elastic cover is disposed on the end portion and covers the groove. The tip base includes a head part and a neck part. A gap is formed between the head part and the elastic cover. The neck is disposed in the groove and is suitable for moving within the groove. When the tip base receives pressure, the tip base moves relative to the shaft, and presses the elastic element to move within the groove.
