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 a through hole in the sheet comprising the inorganic filler and the uncured state thermosetting resin; filling the through hole with a conductive resin; forming a wiring pattern on one surface of a release carrier; mounting an active component and/or passive component on the wiring pattern of the release carrier; superimposing the sheet in which the through hole is filled with the conductive resin onto the surface of the release carrier having the wiring pattern on which the component is mounted; further superimposing a copper foil and heating and pressing in a temperature range in which the thermosetting resin is not cured; burying and integrating the active component and/or passive component into the sheet, thereby forming a core layer; peeling off the release carrier from the core layer; processing the copper foil so that a further wiring pattern is formed; and further superimposing at least one ceramic substrate in which at least two or more layers of a plurality of inner vias and wiring patterns are laminated via an adhesive layer onto at least one surface of the core layer from which the release carrier is peeled off, followed by pressing thereof, the adhesive layer being formed by: processing a mixture comprising at least an inorganic filler and an uncured state thermosetting resin into a sheet; providing a through hole in the sheet comprising the inorganic filler and the uncured state thermosetting resin; and filling the through hole with a conductive resin, thereby curing the thermosetting resins in the core layer and the adhesive layer to be adhered to the ceramic substrate.
