Provided are a capacitive coordinate input device and a capacitive coordinate input method for detecting at high speed the position of an object, such as a human finger or a pen, by detecting a change in capacitance at each intersection of a plurality of electrodes arranged corresponding to two-dimensional coordinates. Tri-state driving is performed such that, immediately after a voltage of a transmitting electrode is changed, impedance of other transmitting electrodes having no voltage change is temporarily increased.
