摘要： According to one embodiment, there is provided an input apparatus comprising a key that is displaceable along a direction; a first detecting circuit that comprises an electrostatic capacitance sensor that detects a variation of an electrostatic capacitance caused by a contact or a proximity of a pressing body with the key; and a second detecting circuit that comprises a first electrode, the second detecting circuit detecting an electric connection of the first electrode to a second electrode that is displaced along the direction as the key is displaced, wherein the input apparatus switches a detecting status thereof exclusively between a first detecting status and a second detecting status to each other in accordance with a displacement variation of the key.
