The invention provides a static capacitance type touchpad capable of inhibiting the detection sensitivity and reducing the influence of a floating conductor. In the static capacitance type touchpad (1), d driving electrode (27) and a detection electrode (28) are distributed on one surface of a substrate (2) in a capacitance coupling manner, a driving voltage is applied to the driving electrode, a detection voltage is outputted via the detection electrode according to capacitance coupling, whether there is an object on the substrate or not is detected based on the detection voltage of the detection electrode, and grounding patterns (5) for avoiding the driving electrode and the detection electrode are arranged on one surface of the substrate. |
