ージ吸収素子。 A pair of electrodes are opposed to each other to form a discharge gap, a voltage non-linear resistor is connected between the electrodes, the discharge gap and the voltage non-linear resistor are connected in parallel, and this is placed in an airtight container together with discharge gas. In the surge absorbing element sealed in the cap, the electrode is formed into a cap shape with side walls rising from the periphery of the base, and this is connected to both sides of the voltage nonlinear resistor so as to cover the resistor. , the tip of the side wall of the electrode is opposed to the voltage non-linear resistor in a space separated by a predetermined distance, so that an excited discharge is generated when the voltage between both surfaces of the voltage non-linear resistor exceeds a predetermined value. A discharge gap is formed between the inner surface of the side wall of the electrode and the voltage nonlinear resistor so that as the discharge current increases, the discharge transfers between the outer surfaces of the side walls of the electrode to form a main discharge. A surge absorption element characterized in that a distance of .
