Abstract
Provided is a shielded printed wiring board that exhibits excellent connection stability even when having a through-hole with a small opening area, and enables a high degree of freedom in circuit design. The shielded printed wiring boardaccording to the present invention includes a printed wiring board, an insulating layer, and a conductive adhesive layerdisposed between the printed wiring boardand the insulating layer. The printed wiring boardincludes a base, a circuit patterndisposed on the base, and an insulating protective layercovering the circuit pattern. The shielded printed wiring board has a through-holefor external grounding that vertically penetrates the insulating layerand the conductive adhesive layer. The conductive adhesive layerhas an extensionextending toward the inside of the through-holeas compared with the insulating layer
