An arc-shaped recess 16 matched with the arc-shaped protrusion 15 is arranged at the center of the conductive adhesive layer 6, and the height of the arc-shaped recess 16 is slightly smaller than that of the arc-shaped protrusion 15, referring to fig. 2. Preferably, the height of the arc-shaped recess 16 is designed to be 0.01-0.03mm lower than the height of the arc-shaped protrusion 15, and the difference is small, so that not only can the arc-shaped recess 16 and the arc-shaped protrusion 15 be attached, but also the conductive adhesive layer 6 and the periphery of the conductive electrode 5 can be attached.
