PROBLEM TO BE SOLVED: To provide a catheter fixing plaster with window having sufficient adhesiveness as a plaster and capable of providing favorable air permeability and moisture permeability in the window part.SOLUTION: A window part 5 is formed on a nonwoven fabric sheet 4 having a pressure-sensitive adhesive layer 3 on one surface of a nonwoven fabric 2. A window part sheet 6 having a polyurethane adhesive layer 8 is prepared on one surface of a polyurethane film 7. The window part sheet 6 is stuck to the other surface side 9 of the nonwoven fabric 2 in such a manner as covering the window part 5 to form a catheter fixing plaster 1 with the window. The other surface side 9 of the nonwoven fabric 2 to which the polyurethane adhesive layer 8 provided on the urethane film 7 is stuck, is smooth and has surface roughness of 7-20 μm. The window part sheet 6 is infallibly stuck to the nonwoven fabric sheet 4.COPYRIGHT: (C)2014,JPO&INPIT【課題】貼付材として充分な接着性を有し、かつ窓部において良好な通気性、透湿性を得ることができる窓付きカテーテル固定用貼付材を得る。【解決手段】不織布2の一面に粘着剤層3を設けた不織布シート4に窓部5を形成する。ウレタンフィルム7の一面にポリウレタン粘着剤層8を設けた窓部シート6を用意する。この窓部シート6を上記窓部5を覆うように上記不織布2の他面側9に貼付して、窓付きカテーテル固定用貼付材1とする。上記ウレタンフィルム7に設けたポリウレタン粘着剤層8を貼り付ける上記不織布2の他面側9は、その表面粗さを7~20μmの平滑なものとし、窓部シート6を不織布シート4に確実に貼付する。【選択図】図2
