ABSTRACT:
In a module with embedded electronic components, connection electrodes are formed on the component mounting surface of a substrate. The electrode portions of each of the electronic components are placed on the individual connection electrodes and connected in fixed relation thereto by using a solder. The electronic components are encapsulated in an encapsulating resin. When the distance between the lower surface of the main body portion of each of the electronic components and the component mounting surface is assumed to be a and the thickness of the portion of the encapsulating resin which is located above the main body portion of the electronic component is assumed to be b, if b/a is set to a value of not more than 6, it becomes possible to prevent, when the module with embedded electronic components is reflow-mounted on a printed wiring substrate or the like, the occurrence of a short circuit failure resulting from the melting and flowing of the solder which causes a short circuit between the two electrode portions.
