摘要： An electronic device includes a wiring substrate, an electronic component mounted on the wiring substrate by soldering, and a case fixed to the wiring substrate so as to cover the electronic component. The case is fixed to the wiring substrate via soldering, and the case and the electronic component are adhered to each other with an adhesive resin supplied through an opening provided in the upper surface of the case. The adhesive resin is applied so as not to contact the wiring substrate such that interface separation does not occur between the adhesive resin and the wiring substrate even when the solder for mounting the electronic component on the wiring substrate is melted and expanded in a solder reflow process. As a result, the generation of short circuiting between terminal electrodes of the electronic component, which is caused by the solder flowing in the portion of the interface separation, is prevented.

摘要： A small high frequency circuit component has very small variations in stray capacitance generated between an inductor electrode pattern and a capacitor electrode pattern. As a result, the variations in the characteristics thereof are also small. The inductor electrode pattern is overlaid with the capacitor electrode pattern in a plan view. That is, when viewed from the lamination direction, the projection of the inductor electrode pattern onto the capacitor electrode pattern is included within the capacitor electrode pattern. More particularly, outer dimensions W1, L1, D1 of the inductor electrode pattern and corresponding outer dimensions W2, L2, D2 of the capacitor electrode pattern satisfy the following conditions, respectively: W2=W1+&Dgr;, where 0.1 mm≦&Dgr;≦1.0 mm, L2=L1+&Dgr;, where 0.1 mm≦&Dgr;≦1.0 mm, and D2=D1+&Dgr;, where 0.1 mm≦&Dgr;≦1.0 mm.
