PROBLEM TO BE SOLVED: To provide a coordinate input device capable of highly accurately measuring an input position even when a pressure is low or touch resistance of a tablet is large. SOLUTION: This device is provided with a pressure sensitive tablet having resistance sheets 1 and 2, a voltage detecting part 4 for detecting the coordinate position of input to the pressure sensitive tablet from a voltage, a change detecting part 6 for detecting the change amount of the voltage detected by the voltage detecting part 4 and a judging part 10 for judging whether the change amount detected by the change detecting part 6 is settled within a prescribed value or not. In this case, when the judging part 10 judges the change amount is within the prescribed value, that coordinate position is fetched as an input coordinate.
