Abstract
An input device includes an input detection unit including a circuit board, an electrostatic electrode on the circuit board for capacitance detection, a light source on the circuit board, a light guide plate provided on the lower side with respect to an operation surface and the upper side with respect to the electrostatic electrode and having a first side surface that faces the light source and a second side surface that does not face the light source, and a frame-shaped light shielding member surrounding the light guide plate and having a light shielding wall in contact with the second side surface. The neighboring first and second side surfaces of the light guide plate form an obtuse angle, the first side surface is perpendicular to upper and lower surfaces of the light guide plate, the second side surface slopes to face downward, and the light shielding wall slopes to face upward.
