Abstract

PROBLEM TO BE SOLVED: To enable a capacitor equipped with lead-out electrodes very accurately disposed in pitch between them to be formed by a method wherein the lead- out electrodes are formed into one piece with an integrating member, connected, and fixed to a capacitor element where metalikons are fixed direct with sheathing resin. SOLUTION: Lead-out electrodes 6 and 7 are held by an integrating member so as to be ensured of being very accurately disposed in pitch between them. The electrodes 6 and 7 are not only surely electrically connected to a capacitor element 2 where metallikons 3 and 4 are fixed through soldering or spot welding but also surely mechanically connected and fixed by application of adhesive resin and encapsulating resin 8. An external force applied to the lead-out electrodes 6 and 7 is dispersed by the integrating member 5, so that a mechanical stress is restrained from concentrating on a local spot on the encapsulating resin 8, and the encapsulating resin 8 is kept uniformly high in mechanical strength as a whole.
