ABSTRACT:
A biosensor is provided, which can measure an analyte in a sample with high precision. The biosensor is produced by disposing a electrode system including a working electrode12and a counter electrode13on a substrate11, and then forming a reagent layer16containing a reagent and particulates on the electrode system. The influence of the impurities in the sample on the electrode system can be eliminated by the particulates. The average particle diameter of the particulates preferably is in the range from 0.1 to 45 μm.
