The disclosed capacitive sensing device has first conductive lines, second conductive lines and electrical conductors. The first conductive lines are electrically isolated from each other, the second conductive lines are electrically isolated from each other and electrically isolated from and stacked with the first conductive lines to form numerous intersecting points, and the electrical conductors are electrically isolated from each other and correspondingly crossing the first and the second conductive lines and being around the intersecting points. Herein, the electrical conductors are electrically isolated from the first and second conductive lines. When an electrical signal is driven to a first conductive line, the first conductive line is capacitive coupled to the second conductive lines which intersecting mutually, and the electrical conductors crossing the first conductive line are respectively capacitive coupled to the first conductive line and the mutually intersecting second conductive lines to provide a higher compound capacitance.
