| abstract |
The present invention relates to a biosensor comprising a working electrode base plate 11 , a counter electrode base plate 14 and a reagent layer containing at least an enzyme and an electron mediator, wherein a working electrode 12 disposed on the working electrode base plate and a counter electrode 15 disposed on the counter electrode base plate are positioned so as to mutually face and a terminal of a measuring device can be brought in contact with terminals 13, 16 of both electrodes from through-holes 25, 24 . Such a biosensor can produce highly reliable and accurate measuring results with only a small amount of a sample. |
