The base protective layer is a thin film of metal oxide containing at least one of magnesium oxide, strontium oxide, calcium oxide, and barium oxide. The particle layer is formed in a manner that single-crystal particles of magnesium oxide having a peak of emission intensity at 200-300 nm two times or higher than another peak of emission intensity at 300-550 nm in the emission spectrum in cathode luminescence emission are stuck on the base protective layer.
