Summary:PROBLEM TO BE SOLVED: To provide an electromagnetic wave shield sheet which has print visibility, adhesion of printing ink, and an insulation layer excellent in ink resistance and also which, when laminated on FPC, has excellent insulation reliability and low repulsive force.SOLUTION: An electromagnetic wave shield sheet is characterized in that an insulating transparent resin layer, a black layer and a conductive adhesive layer (I) are laminated in this order, and the surface of the transparent resin layer has a contact angle with water which is 60 to 110°.SELECTED DRAWING: Figure 2 【課題】本発明は、印字視認性、印字用インキの密着性、およびインキ耐性に優れた絶縁層を有し、ＦＰＣに張り合わせた場合において、絶縁信頼性に優れ、反発力が低い電磁波シールドシートを提供することを目的とする。【解決手段】前記課題は、絶縁性透明樹脂層、黒色層、および導電性接着剤層（Ｉ）の順に積層され、前記透明樹脂層の表面は、水との接触角が６０〜１１０°であることを特徴とする電磁波シールドシートにより解決される。【選択図】図２
