The input device of the invention includes: a lower sheet on which four resistors are formed in a manner that each two of them with a center put in between are placed to face each other circumferentially with a spacing of about 90°; an upper sheet overlying the lower sheet with a spacing, on which conductors are formed to face the respective resistors; elastic bodies disposed over the upper sheet to face the respective conductors; and an operation member to retain upper parts of the elastic bodies. And, when the operation member is pressed downward, the elastic bodies are brought into contact with the resistors with interventions of the conductors on the upper sheet.
