    Abstract: An adhesive for electroless plating is composed of at least one kind of fine powders selected from either a cured heat resistant resin or an inorganic material and easily soluble in a predetermined solution and a heat resistant resin solution sparingly soluble in the predetermined solution by curing treatment. The adhesive for electroless plating in which the above fine powders are dispersed in the above uncured heat resistant resin solution, is coated on a circuit board, dried and cured to form an adhesive layer. When the above predetermined solution contacts with the surface of the adhesive layer, its surface is roughed to be formed a plating film having an excellent adhesiveness by electroless plating.

    Abstract: A wiring substrate includes a core substrate having a cavity penetrating through the substrate, an electronic component accommodated in the cavity such that the component is positioned closer to a first surface of the substrate than a second surface of the substrate, a sealing resin filling the cavity of the substrate such that the sealing resin is covering a surface of the component on a second surface side of the substrate and that the cavity of the substrate has a portion not filled with the sealing resin on the second surface side of the substrate, and resin insulating layers including a first resin insulating layer laminated on the first surface of the substrate and a second resin insulating layer laminated on the second surface of the substrate such that a portion of the second resin insulating layer is filling the portion of the cavity not filled with the sealing resin.

    Abstract: A wiring board includes a first interconnect structure including a first interconnect layer, and a first insulating layer including a non-photosensitive thermosetting resin as a main component thereof, a second interconnect structure including second interconnect layers, and second insulating layers including a photosensitive resin as a main component thereof, and laminated on the first interconnect structure, and an encapsulating resin layer including a non-photosensitive thermosetting resin as a main component thereof, and laminated on an uppermost second insulating layer. An uppermost second interconnect layer includes a pad protruding from the uppermost second insulating layer. The encapsulating resin layer exposes a top surface of the pad, and covers at least a portion of a side surface of the pad. Thermal expansion coefficients of the first insulating layer and the encapsulating resin layer are lower than that of the second insulating layers.
