Abstract

An input devicecomprises a sensor circuitwhich includes a pressure-sensitive sensorand a first fixed resistorwhich is electrically connected in series to the pressure-sensitive sensor. A resistance value Rof the first fixed resistorsatisfies the following expression (1). In the expression (1), Ris a resistance value of the pressure-sensitive sensorwhen ½ of the maximum working load of the pressure-sensitive sensoris applied, and Co is a resistance correction coefficient within the range of 1/16 to 1/1.  (1)
