An input device includes a touch panel configured to be displaceable in vertical direction and to be urged upwardly toward an original position in a non-depressed state, a depression start detector that detects a start of a depression manipulation of the touch panel while the touch panel is depressed and displaced downward, a determination manipulation detector that detects a determination manipulation based on the touch panel is displaced to a position which is lower than a position where the depression start detector detects the start of the depression manipulation, and a decision unit that stores the touch position when the depression start detector detects the start of the depression manipulation, and thereafter decides that the determination manipulation has been conducted at the stored touch position when the determination manipulation detector detects the determination manipulation.
