Abstract
The electronic component of the present invention includes a case having an opening, an electronic component element and electrolytic solution disposed in the case, and a sealing member disposed so as to seal the opening. The sealing member has elasticity and is formed of a cross-linked structure of compound. The compound contains butyl rubber polymer as main component, phenol-based additive, and silane-based additive. Accordingly, the sealing member is improved in air-tightness, and the volatilization of the electrolytic solution becomes lessened. Further, an electronic component having such sealing member ensures excellent mounting ability. As a result, it is possible to obtain an electronic component capable of assuring excellent reliability for a long period of time even in a high temperature atmosphere and under high-temperature high humidity conditions.
