Patent ID: 7911042

Claim:
A package comprising: a package body including: a substrate; an electronic component mounted on a first surface of the substrate; a sealing resin layer for sealing the electronic component; and a shield case including: a portion for substantially covering a surface of the sealing resin layer, two side portions extending generally transverse to the portion, each of the two side portions substantially covering a respective side of the package body formed by the sealing resin layer and the substrate, and an opening defined by the portion and the two side portions, the opening having a predetermined size for inserting another side of the package body formed by the sealing resin layer and the substrate, and a stopper extending from the portion between the two side portions opposite the opening to prevent excessive insertion of the package body when the package body is inserted through the opening the shield case being made of metal and having an inverted U-shape in a cross-sectional view, wherein a lower end of the side portion is bent at a bend point to form a bent part that extends back toward a second surface of the substrate opposite to the first surface, so that a portion of the side near the bend point and the bent part of the shield case form a “V” -shape, with an end of the bent part being closer to the second surface than the bend point when viewed in a direction toward the second surface, so that the end of the bent part abuts on and contacts an area on the second surface to attach the shield case to the substrate, and wherein the bent part has an elastic force toward the second surface when the end of the bent part abuts on and contacts the area on the second surface.
