Abstract
An electrochemical measuring apparatus which essemtially comprises an asymmetric semipermeable membrane mounted on an immobilized enzyme membrane of an enzyme electrode, said asymmetric semipermeable membrane being essentially formed of a thin semipermeable layer exposed to the outside for contact with a liquid to be measured and an inner adjacent thick porous layers, and can measure an organic ingredient such as glucose contained in blood or serum with high sensitivity in a short time and moreover has a prominent durability.
