A capacitor including a ceramic body, a glass layer formed on each of opposite surfaces of the ceramic body, and a first metallic layer formed on the glass layer. Preferably, a lead terminal is connected to the first metallic layer or to a second metallic layer which is provided on the first metallic layer, by use of solder containing Pb in an amount of 2.5 wt. % or less. Preferably, a lead terminal which is plated with a substance containing Pb in an amount of 5 wt. % or less is soldered onto the first metallic layer or the second metallic layer.

Capacitor

A pulse generating capacitor is provided in which a capacitor element has electrodes provided on the front and rear faces thereof, and lead terminals connected to the electrodes by means of bonding members. The bonding members can contain Ag as a major component with a ZrO powder added thereto at a content of about 20% to 60% by volume. The capacitor solves a problem of crack generation on the capacitor element in response to thermal cycling, while maintaining the effects of preventing its pulse voltage from being decreased and enhancing the bonding strength of its lead terminals.
