Claim 3:
4. A detection device comprising:
drive electrodes each of which is configured to be provided with a drive signal; and
detection electrodes opposed to the drive electrodes and configured to generate capacitance between the detection electrodes and the drive electrodes,
wherein the drive electrodes or the detection electrodes include
a first electrode extending in a first direction, and
a second electrode that is disposed at a predetermined interval from the first electrode in a second direction intersecting the first direction and is line-symmetric to the first electrode about an axis of symmetry along the first direction,

wherein the first electrode includes
a first extension part extending in a third direction,
a second extension part extending in a fourth direction, and
a first coupling part through which the first extension part and the second extension part are coupled to each other, and

wherein the second electrode includes
a third extension part extending in the fourth direction,
a fourth extension part extending in the third direction, and
a second coupling part through which the third extension part and the fourth extension part are coupled to each other.
