A coordinate input device of the present invention includes a base having a deformation sensor; a stick that stands upright with a specified height from the base; a rubber cap that can be press-fitted on the stick; and a pressure sensor that can be controlled by pushing a control section formed at the upper end of the rubber cap. The rubber cap has a dome-shaped cavity in the control section. When the control section is pushed, the cavity is elastically deformed to make the pressure sensor operative.
