PURPOSE:To enable the measuring of multi-item ion activities with one operation by providing at least one independent porous liquid distribution member on each of a plurality of solid electrode couples having different ion selection layers. CONSTITUTION:A plurality of solid electrode couples 26 having ion selection layers on the outer most layers are retained and housed in a support frame plate 28 with a partition 29 adapted to fasten the electrodes while electrinically insulating adjacent ones. A water non-permeating member layer 31 with a hole 3 for feeding liquid to a fixed position on each electrode is provided each on the solid electrode couples and a porous liquid distribution member 32 communicating with different ion selection layers is provided to distribute liquid to the liquid feed hole 31. A porous bridge 38 is provided integral on the porous liquid distribution member 32 or a liquid storage tank 34 to achieve an electric conduction between a liquid to be inspected and a standard liquid spotted on the porous liquid distribution member 32 or the liquid storage tank 34 through permeation. |
