PROBLEM TO BE SOLVED: To provide a surge absorption element that can suppress deterioration in discharge characteristics caused by the adhesion of impurity gas on the surface of a discharge electrode and a film, has a long life, and has a high response speed when an impulse (surge) current is applied. SOLUTION: Openings at both ends of a case member 12 are airtightly sealed with a pair of lid members 14, 14 also serving as the discharge electrode to form an airtight envelope 16; discharge gas is sealed into the airtight envelope 16; a discharge gap 22 is formed between discharge electrode sections 18, 18 in the lid members 14, 14; a plurality of trigger discharge films 28 are formed on an inner-wall surface 24 in the case member 12 while both the ends of the plurality of trigger discharge films 28 separate the lid members 14, 14 and a minute discharge gap 26; and further the film 30 containing titanium carbide baked at 100-1,000°C and potassium molybdate is formed on the surface of the discharge electrode section 18.
