An electrolyte concentration measurement device includes a measurement unit that includes an ion selective electrode, a reference electrode and a potential measurement unit; a record and calculation unit that obtains an ion concentration of an internal standard liquid or a specimen; and a concentration value correction/determination unit that determines whether the ion concentration of the internal standard liquid is within a preset value range, and corrects an ion concentration value of the internal standard liquid obtained by the record and calculation unit, in which the measurement unit includes an internal standard liquid bottle storage unit storing a plurality of bottles, and the concentration value correction/determination unit corrects the obtained ion concentration of the internal standard liquid after the bottle is switched, by using information of the ion concentration before the bottle accommodating the internal standard liquid is switched, when a bottle is switched among a plurality of bottles accommodating the internal standard liquid in the internal standard liquid bottle storage unit of the measurement unit.
