Abstract:
1. A method for producing a circuit component built-in module, the method comprising: a first step of processing a mixture containing an inorganic filler and a thermosetting resin into a sheet form having through holes so as to obtain a sheet-like member having through holes; a second step of filling a conductive material in the through holes; a third step of preparing a circuit component package including a circuit component, stacking the sheet-like member and a metal foil in the stated order on the circuit component package, and applying heat and pressure to the obtained stack, so as to embed the circuit component in the sheet-like member; and a fourth step of processing the metal foil so as to form a wiring pattern, wherein the circuit component package includes: a mounting member including a substrate and a wiring pattern provided on the substrate; the circuit component including a component body and an external electrode provided at an end of the component body, the circuit component being arranged on the mounting member; and a conductive material that electrically connects the external electrode with the wiring pattern,
