A touch pen includes a pen barrel having opposite first and second barrel portions. An illuminating unit is received in the first barrel portion, and includes a switch connected to a light source and a power source and operable so as to establish electrical connection between the light source and the power source for enabling the light source to generate a light output which radiates out of the pen barrel via an open end of the first barrel portion. A transparent pen cap has a mounting end portion sleeved removably on the first barrel portion, and a touch tip opposite to the mounting end portion and adapted for touching a touch control panel of a computerized apparatus.
