PURPOSE:To achieve extreme miniaturization, by arranging a porous filament with a hydrophilic surface which have fine pores with the average diameter 0.01-10mum and the capacity of the fine pores exceeding 0.2cc/g as housed in the open tip of a tubule and an electrically insulating resin which contact fixes the filament and a silver-silver chloride wire linked to a connector at the opening of the tubule. CONSTITUTION:A comparison electrode 10 is made up of a tubule 15, a porous filament 11 with a hydrophilic surface as housed in the open tip of the tubule 15, a silver-silver chloride wire 12 as housed with one end thereof contacting the filament 11 which is linked to a connector 13 at the other open end of the tubule 15 while the filament 11 is extending along the tubule 15 and an electrically insulating resin 14 which fills the tip of the tubule 15 to contact fix the silver-silver chloride wire 12 and the filament 1 while closing the tubule 15. The filament 11 herein used has fine pores with the average diameter of 0.01-10mum and the capacity thereof exceeding 0.2cc/g. |
