1. A glucose strip sensor comprising:

  • a non-conductive substrate;

    an electrode section formed on the substrate, the electrode section including an operating electrode and a counter electrode respectively electrically connected to lead terminals by leads;

    a reaction layer formed over the electrode section and being adapted to react with a blood sample;

    a resin plate adapted to define, over the electrode section, a sample receiving space for receiving the blood sample;

    a cover arranged on the resin plate;

    a sample introducing port arranged on a front end portion of the resin plate, the sample introducing port being adapted to introduce the blood sample into the sample receiving space by virtue of capillary phenomenon; and

    discharge ports arranged on opposite sides of the glucose strip sensor and being defined by the resin plate, the discharge ports being adapted to vent air from the sample receiving space,wherein the electrode section further comprises at least one checking electrode arranged near one of the discharge ports, the at least one checking electrode being adapted to check whether or not the blood sample is completely introduced in the sample receiving space.
