PURPOSE:To obtain an electrode having an even carrier film without sag by a method wherein an enzyme membrane electrode with an enzyme immobilized on a carrier film is mounted on a frame body, immersed in a solvent adapted to swell the carrier film and then the solvent removed. CONSTITUTION:For example, a glucose sensor is used as an immobilized membrane electrode. Structurally, the electrode has a platinum layer 2 inside a glucose oxydase immobilized electrode 1 and the glucose oxydase 4 is immobilized in a hole of a carrier film 3 and the surface of the film on the side of a liquid to be inspected. The enzyme electrode 1 is mounted on the body 6 with a casing tube 5 having the platinum layer 2 inside an electrode holder. To improve the response and sensitivity of the sensor, the electrode mounted on the holder is immersed in aceton, methyl ethyl ketone, benzene or the like and then, dried to free the electrode film from sag. |
