BIOSENSOR
First Claim
1. A biosensor measuring an analyte contained in a sample, comprising:
- a lower insulating substrate having formed thereon a working electrode and a reference electrode connected to lead terminals through leads, and an enzyme reactant layer formed on the electrodes to react with the analyte contained in the sample;
a spacer which is interposed between the lower substrate and an upper substrate, is attached to the lower and upper substrates, and has a sample guide area to guide the sample to reach to the electrodes through the enzyme reactant layer; and
an upper insulating substrate which faces the lower substrate through the spacer,wherein a dummy electrode is formed on the lower substrate, the dummy electrode being separated from the working electrode and the reference electrode, fixing the enzyme reactant layer, and being not connected to the leads.

Abstract
A biosensor measuring an analyte contained in a sample is disclosed, including: a lower insulating substrate having formed thereon a working electrode and a reference electrode connected to lead terminals through leads, and an enzyme reactant layer formed on the electrodes to react with the analyte contained in the sample; a spacer which is interposed between the lower substrate and an upper substrate, is attached to the lower and upper substrates, and has a sample guide area to guide the sample to reach to the electrodes through the enzyme reactant layer; and an upper insulating substrate which faces the lower substrate through the spacer, where a dummy electrode is formed on the lower substrate, the dummy electrode being separated from the working electrode and the reference electrode, fixing the enzyme reactant layer, and being not connected to the leads.
