A surge absorber having a longer life by being coated with an oxide layer excellent in chemical stability in a high-temperature region during a sealing step and at main discharging and also excellent in bonding force to a main discharge surface. The absorber comprises a cylindrical ceramics (4) having conductive coatings (3) dividedly formed via a discharge gap (2), a pair of main discharge electrode members (5) disposed facing each other and contacting the conductive coatings (3), and a tubular ceramics (8) filled with the cylindrical ceramics (4) along with a sealing gas (7) thereinside, wherein a glass member is sealed inside the tubular ceramics (8).
