摘要： A reference electrode for use in a flow type measuring apparatus incorporating an immobilized enzyme working electrode, wherein a hydrophilic gel layer is provided on a silver chloride containing layer in order to prevent flow-out of silver ions that are likely to adversely affect enzyme activity, so that the silver chloride containing layer goes into contact through the hydrophilic gel layer with an electrolytic solution containing a substance to be measured.
