1. A detection device comprising:
a substrate; and
a detection electrode including a lower layer portion and an upper layer portion which is on and in physical contact with the lower layer portion, the lower layer portion being between the substrate and the upper layer portion,
wherein the upper layer portion has a first region and a second region which are located continuously,
the first region overlaps the lower layer portion in a plan view and is in physical contact with the lower layer portion, and
the second region does not overlap the lower layer portion in a plan view and is not in physical contact with any conductive member in a thickness direction of the detection electrode.
 
11. A detection device comprising:
a substrate; and
a detection electrode including a lower layer portion and an upper layer portion which is on and in physical contact with the lower layer portion, the lower layer portion being between the substrate and the upper layer portion,
wherein the upper layer portion has a first region and a second region which are located continuously,
the first region overlaps the lower layer portion in a plan view and is in physical contact with the lower layer portion,
the second region protrudes from the first region, and
the detection electrode has a portion which does not have the second region, the portion being a part of the detection electrode and including an entirety of the detection electrode in the thickness direction.
