PROBLEM TO BE SOLVED: To provide an input device capable of reducing power consumption. SOLUTION: A start part 3 is joined with an input part 2 under the input part 2. When a surface sheet 28 is depressed by a finger F or the like, the depression force is transmitted into the input device 1 and an upper electrode 31b and a lower electrode 32b are brought into contact with each other and mutually conducted. A depression signal (interruption signal) generated by the mutual conduction is outputted by interrupting a CPU. The CPU starts the input part 2 on the basis of the interruption signal, and then the coordinate position of the finger F or the like is detected by a sensor circuit in the input part 2. Thereby in a state that the finger F or the like does not depress the surface sheet 28, the input part 2 is not started and scanning operation or the like is not performed by the sensor circuit. Since power is not unnecessarily and uselessly supplied to the circuit as the result, power consumption can be reduced. COPYRIGHT: (C)2006,JPO&NCIPI
