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. |
