description 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 board 1 according to the present invention includes a printed wiring board 10, an insulating layer 22, and a conductive adhesive layer 21 disposed between the printed wiring board 10 and the insulating layer 22. The printed wiring board 10 includes a base 11, a circuit pattern 13 disposed on the base, and an insulating protective layer 14 covering the circuit pattern 13. The shielded printed wiring board has a through-hole 23 for external grounding that vertically penetrates the insulating layer 22 and the conductive adhesive layer 21. The conductive adhesive layer 21 has an extension 21a extending toward the inside of the through-hole 23 as compared with the insulating layer 22.
