Abstract: A coordinate input device comprises a column-shaped body erected on a base, a plurality of sensors produced in a film form, a flexible cable for leading out sensor signals from the sensors, and a transparent heat-shrinkable tube. In this coordinate input device the sensors are affixed with a thermosetting resin on the side surfaces of the column-shaped body; and the tube is put on the sensors and then heated for shrinking, thereby pressing to affix the sensors on the side surfaces of the column-shaped body with the thermosetting resin and also covering the surfaces of the sensors. Then the cap is mounted on the top of the column-shaped body and the tube is fitted in a recess section inside the cap.
