Surge absorbing element
A surge absorbing element has a first electrode, a second electrode, and a ceramic layer. The second electrode is opposed to the first electrode. The ceramic layer has a polycrystal structure including a plurality of crystal grains showing voltage nonlinearity, and is at least partially brought into contact with the first electrode and the second electrode. The ceramic layer has a void inside therein, and surface discharge is generated on surfaces, exposed to the void, of the crystal grains, whereby electric conduction is attained between the first and second electrodes.
