い。In both cases, even if the temperature of the capacitor element 1 rises, the heat generated in the capacitor element 1 is transmitted to the external connection terminal 4a or the external connection terminal 4 via the lead wire 3a. Therefore, a time delay occurs when the temperature sensing element 6 or 7 senses the temperature rise. A capacitor element 1 housed in a metal case 2;
With the external connection terminal 4a or the external connection terminal 4 exposed to the atmosphere outside the metal case 2, the terminal 4a or the terminal 4 easily releases heat and the temperature is easily lowered. As described above, a temperature difference occurs between the capacitor element 1 and the terminal 4a or the terminal 4, and it is difficult to accurately measure the temperature of the capacitor element 1 with the temperature-sensitive element 6 or the temperature-sensitive element 7 attached to the terminal 4a or the terminal 4. .
