PROBLEM TO BE SOLVED: To facilitate replenishment of moisturizing solution to a bioelectrode.SOLUTION: A moisturizing solution replenishing sheet includes: a base material 2 which absorbs and maintains moisturizing solution 1 for giving moisture to a bioelectrode when it comes into contact with the bioelectrode a supporting material 4 which is a sheet maintaining the base material 2 a protective sheet 5 which covers the surface of the base material 2 in order to suppress the evaporation of the moisturizing solution 1 and can exposure the base material 2 by removal or parting while the moisture is given to the bioelectrode and adhesion means 6 for fixing the protective sheet 5 to the supporting material.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】生体電極への保湿溶液の補充を容易にする。【解決手段】保湿溶液補充シートは、生体電極と接触したときに生体電極に湿気を与えるための保湿溶液1を吸水して保持する基材2と、基材2を保持するシート状の支持材4と、保湿溶液1の蒸発を抑制するために基材2の表面を覆い、生体電極に湿気を与える際に除去または裂開によって基材2を露出させることが可能な保護シート5と、保護シート5を支持材に固定する接着手段6とを備える。【選択図】 図1
