| 摘要 |
Provided is an ESD protection device having high operability. The present invention is provided with a multilayer substrate 3 in which a plurality of insulation layers 3a-3g are laminated, a first discharge electrode 1 and second discharge electrode 2 each disposed between different layers of the multilayer substrate 3, and auxiliary discharge electrodes 5 formed between the first discharge electrode 1 and the second discharge electrode 2, the interiors of which are filled with an auxiliary discharge substance. The present invention is configured such that when the multilayer substrate 3 is viewed from the lamination direction of the insulation layers 3a-3g, a plurality, for example, five, auxiliary discharge electrodes 5 are formed in a discharge electrode redundant section 4 in which the first discharge electrode 1 and the second discharge electrode 2 overlap. |
