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 electrode 12 and a counter electrode 13 on a substrate 11 , and then forming a reagent layer 16 containing 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 mum.
