Input device

An input device comprising:

• a first electrode that includes:
• one or more reference potential electrodes;
• and
• two or more sets of transmission electrodes and reception electrodes, the two or more sets each including one of the transmission electrodes and one of the reception electrodes;
• and
• a second electrode that approaches and recedes from the two or more sets in a displacement direction by moving by rotation or translation in a state in which the second electrode faces the first electrode with a predetermined space being provided therebetween,
• wherein the one or more reference potential electrodes face at least a portion of the second electrode as a result of the second electrode approaching at least one set of a transmission electrode and a reception electrode out of the two or more sets,
• the two or more sets include:
• a first set of a transmission electrode and a reception electrode, the first set being disposed in a first region;
• and
• a second set of a transmission electrode and a reception electrode, the second set being disposed in a second region,
• a phase when the first set approaches and recedes from the second electrode is different from a phase when the second set approaches and recedes from the second electrode, and
• wherein the one or more reference potential electrodes are ground electrodes.
