PURPOSE:To obtain a composite material electrode having high sensitivity and nearly independent of the flow rate of a fluid to be measured, by charging a bundle of carbon fibers and an electrically nonconductive resin into a tube and curing the resin. CONSTITUTION:A bundle of carbon fibers is put in a tube of PE or the like and an electrically nonconductive resin such as epoxy resin is charged into the tube. The pref. thickness of the carbon fibers is <=10mum and the bundle is composed of about 500-3,000 carbon fibers. The electrically nonconductive resin is then cured by heating the tube. The resulting composite material electrode contg. carbon fibers is useful as an electrode for measuring a dissolved electrochemically reactive substance such as oxygen in a fluid. |
