Abstract
A biosensor for measuring gas-phase organic chemicals rapidly and accurately. The biosensor includes a thick film electrochemical device having an insulating substrate, electrodes formed on the substrate, connecting pads for the electrodes and an insulating layer, and a responsive membrane formed on the electrode portion of the electrochemical device. The responsive membrane is provided with a moisture-absorbing gel layer in which an enzyme for reacting with the gas-phase organic chemical is immobilized.
