特徴とする避雷器。 A lightning arrester uses conductors patterned on a printed circuit board to limit overvoltage in an electric circuit, and includes a pair of conductors each having a protrusion of the conductor shaped to easily discharge at the tip and facing each other with a distance of a discharge gap. The conductor is provided on a printed circuit board in a spaced apart part of a pair of conductors, and the length of the conductor in the axial direction is at least equal to the discharge gap, and the length from one conductor protrusion along the periphery of the opening to the other conductor protrusion is the creepage. What is claimed is: 1. A lightning arrester comprising: an opening that penetrates a printed circuit board and has a width that is long enough to prevent electric discharge from occurring.
