1. A detection device comprising:
a substrate;
a plurality of drive electrodes disposed at the substrate, each extending in a first direction, and arranged in a second direction intersecting the first direction; and
a plurality of detection electrodes opposed to the drive electrodes, each extending in the second direction, and arranged in the first direction, wherein
each of the drive electrodes and the detection electrodes has a plurality of superimposed portions and a connecting portion connecting the superimposed portions,
one of the superimposed portions of one of the drive electrodes and one of the superimposed portions of one of the detection electrodes are superimposed over each other and extend linearly in a same direction, and
in a planar view from a direction perpendicular to a main surface of the substrate, some of the superimposed portions and some of the connection portions form a first closed region closed annularly, wherein
the detection device further comprises a plurality of first closed regions including the first closed region,
the first closed regions are arranged in the first direction,
a second closed region surrounded by some of the connecting portions is disposed between the first closed regions adjacent to each other in the first direction, and
the second closed region is closed annularly and has a portion where neither the drive electrodes nor the detection electrodes are located.
