Surge protector which includes a film pattern (2) formed on a suitable substrate (1) is characterized in that the film pattern (2) essentially consists of narrow lines (2a, 2b, 2c) which extend parallel and adjacent to each other and are electrically in parallel relationship to each other, and bridges (11-24) between the lines. Advantageously, there are three parallel lines. The resistance of the film pattern (2) is trimmed advantageously by cutting off (T5, T6, T7, T8, T9, T10) one of the lines (2c) between successive bridges.
