    Abstract: A transient voltage protection device includes an element body formed with a cavity inside, a pair of external electrodes on the element body, and a pair of internal electrodes in the element body. The pair of internal electrodes oppose each other. Each internal electrode is connected to a corresponding external electrode of the pair of external electrodes. The element body includes a first inner surface and a second inner surface. The first and second inner surfaces define the cavity and oppose each other. The pair of internal electrodes are exposed to the cavity and disposed on the first inner surface. In a cross section along a direction in which the first inner surface and the second inner surface oppose each other, the first inner surface includes a contour different from a contour included in the second inner surface.

    Abstract: A transient voltage protection device includes an element body formed with a cavity inside, a pair of internal electrodes, and a discharge assistance portion. The pair of internal electrodes are disposed in the element body and include edges. The edges include parts opposing each other in a first direction in the cavity. The discharge assistance portion is in contact with the parts of the edges. Each of the edges includes a first end exposed on an outer surface of the element body and a second end located opposite the first end and including a corner. The discharge assistance portion includes a pair of edges opposing each other in a second direction intersecting with the first direction and exposed to the cavity. The part included in each of the edges does not include the corner.

    Abstract: A transient voltage protection device includes: an element body; a cavity portion provided in the element body; a pair of internal electrodes disposed in the element body; and a pair of external electrodes connected to the pair of internal electrodes. The pair of internal electrodes extend along a first direction and face each other in a second direction intersecting the first direction. The cavity portion includes a gap region located between the pair of internal electrodes in the second direction. A tip portion of at least one of the pair of internal electrodes is in contact with only the element body.
