PURPOSE: A pointing device including a waterproof member is provided to prevent malfunction or performance degradation even if a terminal device is exposed to moisture by providing a tight waterproof structure between the terminal device and a pointing device. CONSTITUTION: A dome switch is included in a lower portion of a substrate(300). A sensor unit(200) is formed on the substrate. A waterproof member(100) is formed into a structure that surrounds the sensor unit and arranged between a frame(600) and the substrate. The waterproof member is transformed by elasticity when a pointing device moves and restored when the pointing device returns to an original state. The waterproof member connects the substrate and the frame. A part of the waterproof member is exposed to around the sensor unit. |
