1. an analytical tool, including:

  • Substrate;

    First electrode, it is formed on aforesaid substrate and comprises the band electrode of working electrode;

    Second electrode, it is formed on aforesaid substrate and comprises the band electrode to electrode;

    WithTwo first restriction elements, it is for limiting the contact area with sample contacts on above-mentioned working electrode,Described analyzer has the second restriction element, and this second restriction element is for limiting above-mentioned working electrode and above-mentioned to carrying out the effective area that electronics is given and accepted and two slits (23A, 23B) formed at least one party in electrode,Wherein,Length on the above-mentioned working electrode of each leisure of above-mentioned two slit and the above-mentioned first direction that electrode is arranged side by side less than the width of above-mentioned band electrode,Above-mentioned two slit each has main line (23Aa, 23Ba) and by-pass (23Ab, 23Bb), described main line (23Aa, 23Ba) extends along above-mentioned working electrode and the above-mentioned first direction that electrode is arranged side by side, described by-pass (23Ab, 23Bb) extends along the second direction as the direction intersected with above-mentioned first directionAbove-mentioned two first limit element so that restriction working electrode effective area two slits (23A, 23B) in the mode exposed of main line (23Aa, 23Ba) compare the separation distance of described main line (23Aa, 23Ba) and configure more at spaced intervals, the edge being namely disposed for limiting above-mentioned contact area crosses above-mentioned by-pass.
