ABSTRACT:
A biosensor and a biosensor measuring apparatus whose performance can be easily determined by an ordinary user are provided. A biosensor100includes a substrate1having a quality deciding section13and a sample receiving section15provided on the substrate1to which a sample is supplied. The quality deciding section13includes a moisture absorbing material changed in color through absorption of moisture. The sample receiving section15has a reagent section7including an enzyme reacted with a test substance as a substrate. The quality deciding section13includes a recess17formed in the substrate1, the moisture absorbing material16disposed in the recess17and a film18with no air permeability substantially covering the opening of the recess17and closely adhered to the moisture absorbing material16. Cobalt salt is used as the moisture absorbing material16.
