Abstract
A stylus provided in the present invention is utilized to input accompanying with a capacitive touch panel. The stylus includes a housing, a magnetic core and a pen tip. The magnetic core is disposed inside the housing. The magnetic core has an axial through hole which defines a bore diameter. The pen tip is disposed at an end of the housing, and the pen tip is made of conductor. The pen tip has a rod portion and a contacting portion. The rod portion is inserted into the axial through hole, and the contacting portion protrudes from the pen shell. The contacting portion has a cylindrical surface and a part spherical surface. The cylindrical surface defines a first diameter; the part spherical surface defines a second diameter. The first diameter is less than the second diameter, and the first diameter is greater than or equal to the bore diameter.
