An input device includes multiple operators disposed in a visible state on an operation surface, a protrusion protruding from the operation surface, and a detector that detects an input of an operation performed on each of the operators when a detection position of an input object is included in a detection range set for each operator. The multiple operators include a first operator disposed near the protrusion and a second operator disposed at a position farther away from the protrusion than the first operator. An extension amount by which the detection range for the first operator is extended in a direction away from the protrusion from a visible position of the first operator is set to be larger than an extension amount by which the detection range for the second operator is extended in the direction away from the protrusion.
