1. A capacitive input device comprising:
a surface member;
a soft member; and
a sensor sheet configured to detect a change in capacitance,
wherein the surface member has an operation area on which a touching operation is to be performed,
wherein the soft member is provided between the operation area and the sensor sheet,
wherein the sensor sheet includes a sensor electrode at a position corresponding to the operation area,
wherein when the operation area is pressed in a touching operation, the surface member and the soft member are displaced toward the sensor sheet and the sensor electrode detects the capacitance,
wherein the soft member includes a conductive portion provided inside the soft member,
wherein the conductive portion increases a value of the capacitance to increase detection sensitivity in a region between the operation area and the sensor electrode, wherein the conductive portion is formed from a conductive medium contained in the soft member, the soft member being formed from a polymer matrix, and
wherein the conductive portion is an oriented portion in which the conductive medium is oriented in the soft member.
