Abstract
A pointing device is provided which facilitates the assembly, achieves downsizing and has a long life. Magnetic sensors 21 are placed symmetrically two by two along an X axis and Y axis on a printed circuit board 24. A switch 28 is placed on a silicone resin 23 side surface of the printed circuit board 24 to provide a switch function achieved by depressing a magnet cover 25 toward the magnet 22. The pointing device, a device for outputting coordinate values of an input point, can not only output the coordinate values, but also make a decision by the switch function. A silicone resin 23 is easy to deform caused by an external force, and returns its initial state without the applied external force as soon as the external force is removed.
