<P>PROBLEM TO BE SOLVED: To provide a biosensor capable of well venting air in a specimen supply passage, regardless of the viscosity of the supplied specimen sample, capable of fully sucking the specimen sample and having fine air holes. <P>SOLUTION: The specimen supply passage 7 for sucking the supplied specimen sample in the gap between first substrate and second substrates 8 is formed, by laminating at least the first and second substrates 1 and 8 and a reagent layer 5 reacted with a component in the specimen sample is arranged in the specimen supply passage 7 while the air hole 9, of which the caliber of the opening part 9b on one side facing to the specimen supply passage 7 of the second substrate 8 is larger than that of the opening part 9a on the other side of the second substrate, is provided to the second substrate 8. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
