A touch-sensitive coordinate input apparatus includes a plurality of regions (3,4) on a substrate (1), each region being defined by four electrodes (2A, 2B, 2C, 2D; 4A, 4B, 4C, 4D) disposed rectangularly, and also includes a dielectric (6) disposed across the four electrodes in each region (3, 4). A position-detecting mechanism (7,8) obtains position information of a touch operation by calculating changes in capacitance of the four electrodes (2A, 2B, 2C, 2D; 4A, 4B, 4C, 4D) for every region caused by the touch operation to the dielectric (6) within the region (3,4), and a compound-processing mechanism (9) conducts a calculation processing based on the position information in at least two of the plurality of regions (3,4).
