In order to improve operability when operating a target key, an input device has a plurality of keys arranged in a column direction. Each of the plurality of keys comprises a key indication mark (211) formed on an operation surface and an electrode plate (221) of a capacitive touch sensor disposed behind the operation surface, and the electrode plates (221a, 221b and so on) has a shape in which the top edge and the bottom edge are V-shaped and bend downwards so that the center of gravity of the electrode plate is positioned downwards in the column direction from a center of a minimum rectangle region enclosing the corresponding key indication marks (221a, 221b and so on).
