Abstract:
1. A method for producing a component built-in module, comprising: processing a mixture comprising at least an inorganic filler and an uncured state thermosetting resin into a sheet; providing the sheet comprising an inorganic filler and an uncured state thermosetting resin with a through hole; filling the through hole with a conductive resin; mounting an active component and/or passive component on a copper foil; superimposing the sheet in which the through hole is filled with a conductive resin onto the surface of the copper foil on which the components are mounted; furthermore superimposing a copper foil; burying the active and/or passive component in the sheet, followed by heating and pressing the sheet material, thereby curing the thermosetting resin and the conductive resin in the sheet; then processing the copper foil on the outermost layer into a wiring pattern, thereby forming a core layer; providing a through hole in a sheet comprising an inorganic filler and an uncured state thermosetting resin or an organic film having adhesive layers on both surfaces; superimposing a copper foil, and the sheet or the organic film in which the through hole is filled with a conductive resin onto at least one surface of the core layer, followed by heating and pressing thereof so as to be integrated onto each other; and processing the copper foil into a wiring pattern.
