Displacement detecting apparatus, lens barrel, and imaging apparatus

A lens barrel comprising:

• a fixed member;
• a movable member movable relative to the fixed member;
• a first electrode including a base electrode segment and a plurality of detecting electrode segments;
• a second electrode having a predetermined periodic pattern and movable relative to the first electrode;
• a detector configured to detect a displacement based on a capacitance between the first electrode and the second electrode;
• and
• a wiring configured to connect the plurality of detecting electrode segments and the detector with each other,
• wherein a portion of the wiring facing the second electrode is located opposite to the second electrode with respect to the base electrode segment.

An imaging apparatus comprising:

• a lens barrel;
• an image sensor configured to photoelectrically convert an optical image formed via an optical system in the lens barrel,
• wherein a lens barrel includes:
• a fixed member;
• a movable member movable relative to the fixed member;
• a first electrode including a base electrode segment and a plurality of detecting electrode segments;
• a second electrode having a predetermined periodic pattern and movable relative to the first electrode;
• a detector configured to detect a displacement based on a capacitance between the first electrode and the second electrode;
• and
• a wiring configured to connect the plurality of detecting electrode segments and the detector with each other,
• wherein a portion of the wiring facing the second electrode is located opposite to the second electrode with respect to the base electrode segment.
