Abstract

An ultrahigh-frequency electronic component has an ultrahigh-frequency chip encased in a molded-resin package. The ultrahigh-frequency electronic component includes a first sealing layer encasing the ultrahigh-frequency chip therein and a second sealing layer encasing the first sealing layer therein. The first sealing layer contains a number of voids or minute air bubbles therein which are effective in reducing the permittivity of the first sealing layer. A method of manufacturing the ultrahigh-frequency electronic component is also disclosed.
