Abstract
A first detection electrode is provided on an insulating layer. A second detection electrode is provided away from the first detection electrode on the insulating layer, and forms a capacitance together with the first detection electrode. The protection layer covers the first detection electrode and the second detection electrode, has a thickness d satisfying 1 μm≤d≤10 μm, and is made of zirconia or alumina. The protection layer is a sintered body.
