Patent ID: 7183498

Claim:
A high-frequency module comprising: a printed circuit board; a plurality of electronic components mounted on at least one of an upper face and a lower face of the printed circuit board; a first circuit block including the electronic components; a second circuit block adjacent to the first circuit block; and a shield case for covering the first circuit block and the second circuit block, wherein: the shield case includes: a ceiling section for covering the first and second circuit blocks; a side plate orthogonally bent from an outer periphery of the ceiling section; a connection section that is provided at a tip end of the side plate and that is connected to the printed circuit board; and a first barrier that is provided at an intermediate part of the ceiling section to be orthogonal to the ceiling section and segmentalizes the ceiling section, the first barrier has: a first wall provided by being bent from one of segmentalized parts of the ceiling section; a second wall that is opposed to the first wall and that is provided by being bent from the other of the segmentalized parts of the ceiling section; and a linkage section for linking a tip end of the second wall to a tip end of the first wall, the shield case is provided with notches at a part at which the first wall, the ceiling section and the side plate cross one another and a part at which the second wall, the ceiling section and the side plate cross one another, the side plate includes a division section, to divide the side plate into neighboring side plate sections, extending from the notches in a downward direction; a boundary between the first circuit block and the second circuit block is provided at a position corresponding to the first barrier; and the connection section is connected to a ground of the first circuit block or the second circuit block.
