Zusammenfassung:	To provide a transient voltage protection device capable of improving transient voltage protection characteristics.SOLUTION: A transient voltage protection device includes an element body 2, a pair of internal electrodes arranged in the element body 2 so as to face each other, and a discharge auxiliary portion 7 disposed within the element body 2 so as to be in contact with the pair of internal electrodes. The discharge auxiliary portion 7 has a plurality of metal particles M. The particle size d95 of the plurality of metal particles M at which the cumulative frequency in the particle size distribution is 95% is 3.5 μm or less.SELECTED DRAWING: Figure 6 【課題】過渡電圧保護特性を向上し得る過渡電圧保護デバイスを提供する。【解決手段】過渡電圧保護デバイスは、素体２と、互いに対向するように素体２内に配置されている一対の内部電極と、一対の内部電極に接するように素体２内に配置されている放電補助部７と、を備えている。放電補助部７は、複数の金属粒子Ｍを有している。複数の金属粒子Ｍの、粒度分布における頻度の累積が９５％となる粒径ｄ９５は、３．５μｍ以下である。【選択図】図６
