Abstract
According to one embodiment, a detection device includes a substrate, detection electrode, terminal formed of a metal material, lead, coating layer, conductive adhesion layer, and circuit board. The lead connects the electrode and the terminal. The coating layer covers the electrode and the lead, and partly covers the terminal. The adhesion layer covers a part of the terminal exposed from the coating layer and covers a part of the coating layer. The circuit board is connected to the terminal with the adhesion layer interposed therebetween. At least in an overlapping area where the adhesion layer covers the coating layer, an area of the metal material per unit area is smaller than that of the other area of the terminal.
