<P>PROBLEM TO BE SOLVED: To provide a lithium ion concentration meter and a method of measuring lithium ion concentration and an electrode for measuring lithium ion concentration for improving the measuring sensitivity and measuring accuracy of the lithium ion concentration. <P>SOLUTION: The lithium ion concentration meter for measuring lithium ion concentration in liquid to be inspected includes: a pair of electrodes arranged such that liquid holding materials for holding liquid to be inspected are interposed from the both sides; voltage application means for applying a voltage between the pair of electrodes; and current measurement means for measuring currents running between the pair of electrodes. Each of the pair of electrodes includes: an active substance layer for ejecting or absorbing the lithium ion according as a charge is transferred; and a lithium ion transmission layer arranged on the first face side of the active substance layer for selectively transmitting the lithium ion from among the plurality of types of ion. <P>COPYRIGHT: (C)2012,JPO&INPIT |
