Metallic tines 3 and 4 are formed on both end faces. 5 and 6 are terminals connected to metal lines 3 and 4, respectively. Reference numeral 7 denotes a switching element connected between the metallic contacts 3 and 4 and brought into contact with the side surface of the capacitor element 2. As shown in FIG. 2, this switching element 7 consists of a flat pressurized conductive rubber 8 and a tin layer which is insulated from both sides of the pressurized conductive rubber 8 (laminated and sandwiching the conductive rubber 8). It consists of flat braided wires 9 and 10 made of plated copper wire, and an outer device 1 made of silicone rubber that covers the whole of them.

に防止される。According to the above-mentioned embodiment, when a large current flows through the capacitor element 2 and it is heated, the internal pressure increases, and the capacitor element 2 normally undergoes a deformation in which its side surfaces expand as shown in FIG. 2] When the side surface of the sensor element 2 expands, the switching element 7
Since it is bent into a dogleg shape, force is applied to the pressurized conductive rubber 8, and the resistance between the flat braided wires 9 and 10 becomes 1Ω or less. As a result, the connection between terminals 5 and 6 is metallic: 1, 3 and 4.
Since it is connected by the switching element 7 via the switching element 7, it is short-circuited. Therefore, destruction of the capacitor element 2 is reliably prevented.
