Provided is an electrolyte concentration measurement device that uses a reduced amount of liquid for measurement and makes it possible to significantly reduce retained sample liquid and to maintain the high measurement accuracy of conventional ion-selective electrodes while achieving a stable seal with no spaces during ion-selective electrode flow path connection. In a flow type ion-selective electrode, a seal material used in a flow path connection part can be adhered up to the vicinity of a flow path hole, there is a gap definition material for maintaining a prescribed gap between electrodes and preventing the seal material from being excessively crushed, and an electrode housing has a structure corresponding to the seal material so that the seal material can be aligned and held. 提供电解质测定装置，其维持了现有的离子选择性电极的较高的测定精度，并在离子选择性电极的流路连接时实现无间隙而稳定的密封，减少了测定中使用的液量且能够使滞留的试样液大幅减少。在流动型离子选择性电极中，在流路连接部使用能够紧贴到流路孔附近的密封件，具有使电极间的间隙保持恒定而防止密封件被过度挤压变形的间隙规定件，电极壳体也具有与密封件对应的构造而能够实现密封件的对准和保持。
