Abstract
Provided is an input device which has excellent operability by not requiring a finger to be released from a key during operation requiring the finger to shift and preventing the finger from touching a plurality of keys at the same time. A key () surrounding a selection key () is arranged. On a board (), four metal domes () are arranged at positions corresponding to the four positions, i.e., upper, lower, right and left positions, of the key (). A touch sensor () is arranged on an upper layer above the metal dome (). The touch sensor () is brought into contact with a touch sensor presser (), and an electrical value (for instance, a resistance value) is changed corresponding to shift of the finger on the key (). When the key () is strongly pressed down, the top of the metal dome () is pressed into the substrate () side and electricity is carried between contact points ().
