Method of producing circuit component built-in module with embedded circuit component

摘要

A circuit component built-in module can be produced by filling a conducting material in through holes of a sheet-like member, stacking the sheet-like member and a metal foil on a circuit component package, and applying heat and pressure to embed the circuit component in the sheet-like member, and patterning the metal foil. The circuit component package includes a mounting member with substrate and wiring pattern and a circuit component. The circuit component includes a component body and external electrode, with the component body being thinner at a portion on which the external electrode is provided. The external electrode is provided on a surface of the circuit component that is opposed to the mounting member, and the component body is in contact with the mounting member.
