A discharge-type surge absorbing element that absorbs a surge by using the discharge that occurs between a discharge interval arranged within a sealed container filled with a discharge gas. The discharge-type absorbing element is characterized by a plurality of discharge electrodes connected to lead wires and disposed within a sealed container filled with a discharge gas. The discharge electrodes are disposed within the container so that they face each other and so that a discharge gap is formed between the discharge electrodes. The lead wire from each of the discharge electrodes passes through the sealed container and extends externally. A layer is disposed on the inside surface of the sealed container, at least between the lead wires. The layer has good creeping discharge properties and is made from the material in the discharge electrodes. A very small gap is formed between the lead wires and the end of the layer.
