PROBLEM TO BE SOLVED: To provide a base material for a medical patch, which has a good texture and an excellent stretchability.SOLUTION: A base material for a medical patch has a configuration where "a fine fiber layer and a crimped fiber layer containing crimped fibers are laminated and a part of fibers constructing the fine fiber layer enters the crimped fiber layer" and "it has an average fiber diameter of the fibers present on a main surface of the fine fiber layer opposite to the side of the crimped fiber layer smaller than an average fiber diameter of the crimped fiber layer". The fibers present on the main surface of the fine fiber layer opposite to the side of the crimped fiber layer has a round cross-sectional shape, thus it is considered that the base material for the medical patch has an excellent smoothness in the main surface of the fine fiber layer opposite to the side of the crimped fiber layer. Therefore, there is provided a base material for a medical patch having a good texture and an excellent stretchability.SELECTED DRAWING: NoneCOPYRIGHT: (C)2020,JPO&INPIT【課題】風合いが良く伸張性に富む貼付薬用基材の提供を目的とする。【解決手段】「細繊維層と捲縮繊維を含んでいる捲縮繊維層が積層してなると共に、前記細繊維層を構成する繊維の一部が前記捲縮繊維層へ入り込んでいる」構成を備えており、「細繊維層における捲縮繊維層側と反対側の主面上に存在する繊維の平均繊維径は捲縮繊維層の平均繊維径よりも小さい」貼付薬用基材における、細繊維層における捲縮繊維層側と反対側の主面上に存在する繊維の断面形状が円形であることによって、細繊維層における捲縮繊維層側と反対側の主面の平滑性に優れた貼付薬用基材であると考えられる。そのため、風合いが良く伸張性に富む貼付薬用基材を提供できる。【選択図】なし
