ABSTRACT:
An enzyme electrode for a chemical sensor includes an electrode including a pair of working electrodes, a reference electrode and a counter-electrode. A first film is formed on one of the working electrodes, which includes a polyvinyl alcohol and a surface-active agent. A second film is formed on the other working electrode including polyvinyl alcohol, surface-active agent and enzyme. An overcoat film of high polymer electrolyer including a pH buffer is formed on the first and second films. The polymerization degree of the polyvinyl alcohol is from 300 to 3000 and the high polymer electrolyer may be alginic acid, polystyrene sulfonic acid or polyacrylic acid, and the pH buffer is a positive ion having a valence of 1.
