An improved structure of touch stylus includes a barrel, a sleeve, a positioning bar, a non-conductive head, and a flexible metal fabric. The sleeve and barrel are assembled together as a unitary member and the positioning bar is received in the sleeve. The non-conductive head receives a non-conductive body fit therein and the non-conductive body is fit over the positioning bar so that the non-conductive head is supported by the non-conductive body when the flexible metal fabric that surrounds outside the non-conductive head is put in contact with the a touch screen. As such, the non-conductive head is provided, internally, with a supporting force that prevents the non-conductive head from not resuming the original shape after being pressed down by the contact and thus improving accuracy of touch and extending the lifespan.
