PROBLEM TO BE SOLVED: To provide a moisture-permeable and waterproof sheet capable of effectively preventing intrusion of rainwater permeating a building material containing an insect repellent and/or an antiseptic agent.SOLUTION: A moisture-permeable and waterproof sheet is obtained by applying surface treatment to a porous hydrophobic resin sheet or a hydrophobic nonwoven fabric by a treatment agent containing fluoroalkane in which a radical polymerizable group and/or a hydrolytically condensable group are/is coupled by direct coupling or via a linker. The moisture-permeable and waterproof sheet can be suitably utilized as a substrate for a building material (furring strips, a batten cleat and the like) containing an insect repellent and/or an antiseptic agent. 【課題】防虫剤及び／又は防腐剤を含有する建材を浸透する雨水の浸入を有効に防止できる透湿防水シートを提供する。【解決手段】多孔質の疎水性樹脂シート又は疎水性不織布に対して、直接結合又はリンカーを介してラジカル重合性基及び／又は加水分解縮合性基が連結したフルオロアルカンを含む処理剤で表面処理することにより、透湿防水シートを得る。この透湿防水シートは、防虫剤及び／又は防腐剤を含有する建材（胴縁、桟木など）の下地として好適に利用できる。【選択図】なし
