    Abstract: The present invention relates to an electrochemical biosensor with improved hematocrit measurement accuracy for measuring blood glucose. According to the present invention, an electrochemical biosensor including a first electrode part for correcting a measured hematocrit value and a second electrode part for measuring a glucose concentration is effective in improving accuracy of a measured hematocrit value and in more improving accuracy of a measured blood glucose concentration using the measured hematocrit values for correction, because an insulation cover is made thinner than a working electrode and an auxiliary electrode, so that areas of a first working electrode and a first auxiliary electrode of the first electrode part exposed to a blood sample become equal; a distance between the first working electrode and the second working electrode becomes constant; and electrode areas are maintained constantly by the insulation cover even when a positioning error occurs during printing.
