A coordinate input apparatus is provided that consumes little power and is capable of properly inputting coordinates without being influenced by a surrounding environment change. The coordinate input apparatus 21 has pressure sensors 3 a , 3 b , 3 c , 3 d, and 3 e that are composed of registers and detect the pressure applied at the time of operation as voltage changes. A switching element 23, 31 that on/off controls a voltage to be applied to the pressure sensors 3 a , 3 b, 3 c , 3 d, and 3 e is provided on the power source side of the pressure sensors 3 a , 3 b , 3 c , 3 d, and 3 e.
