Patent ID: 7140104

Claim:
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, wherein in the circuit component, the component body is shaped so that a first portion of the component body on which the external electrode is provided is thinner than a second portion of the component body, the second portion being a portion on which the external electrode is not provided, and the external electrode is arranged in a region on a side on which the component body is positioned with respect to a reference plane containing a predetermined surface of the component body, the predetermined surface of the component body being a surface of the component body that is to be opposed to a mounting member when the circuit component is mounted on the mounting member, and the circuit component is arranged on the mounting member so that the component body is in contact with the mounting member.
