Abstract
Downward projections made on two side walls of a cap are fitted into recesses in two opposed side faces of a substrate. Lower margins of two end walls of the cap are soldered to ground electrodes provided on a part mounting face of the substrate. Lower margins in the proximity of projections of the side walls of the cap are soldered to ground electrodes provided on the part mounting face above recesses of the substrate. Therefore, it is provided a high-frequency module that can produce a good electromagnetic shielding effect even in a high-frequency band.
