1. A biosensor, comprising:

  • an upper insulating substrate;

    a lower insulating substrate;

    a working electrode and a reference electrode, being formed on the inner surface of the lower insulating substrate;

    spacers interposed between the upper insulating substrate and the lower insulating substrate, the spacers and the insulating substrates being configured to form a sample path via which sample flows;

    an enzyme reaction layer as a reagent is immobilized onto the working electrode and the reference electrode along the sample path in the width direction; and

    ,at least one sensing electrode formed on the upper insulating substrate and the lower insulating substrate, respectively, the sensing electrodes being disposed adjacent to a sample injection port and at the opposite side of the sample injection port, respectively, such that the working electrode and the reference electrode are interposed therebetween and the sensing electrodes are extended substantially from the sample path to a connection terminal to be connected to a socket of a measuring device.
