Abstract
A high-frequency module has an attached shield case. Barrierof the shield case has wallprovided by being bent from ceiling section; wallthat is opposed to walland that is provided by being bent from ceiling section; and linkage sectionfor linking the tip end of wallto the tip end of wall. The shield case further has: a crossing section at which wallcrosses ceiling sectionand side plate; notchesrespectively provided at the crossing sections at which wall, ceiling sectionand side platecross one another; and division sectionextending downward from notchesfor segmentalizing side plate. A boundary between circuit blockand circuit blockis provided at a position corresponding to barrier. Connection sectionis connected to the ground of circuit blockor circuit block. As a result, a module having a superior shielding performance can be provided to prevent leakage of a signal from a circuit provided on the printed circuit board.
