PURPOSE: An electrochemical biosensor strip and a specimen measuring method using the same are provided to use an insulating pattern layer and electrode pattern layer, thereby preventing the interference of two kinds of specimen signals. CONSTITUTION: An electrochemical biosensor strip comprises a bio sensor strip support(100), an electrode pattern layer(200), an insulating pattern layer(300), a reaction pad unit(400), and a bio sensor strip cover(500). The electrode pattern layer is joined on the bio sensor strip support and composed of a recognition electrode pattern layer, a first electrode pattern layer, and a second electrode pattern layer. The insulating pattern layer is joined onto the electrode pattern layer to be laminated and composed of an insulating body, a first reaction region, and a second reacting region. A reaction layer, a separation layer(430), and a distribution layer(440) are successively laminated on the insulating pattern layer. The reaction layer, separation layer, and distribution layer comprise a first membrane filter(410) and a second membrane filter(420). The bio sensor strip cover is joined onto the reaction pad unit and a loading hole(510) for inserting a physiological specimen is formed.
