Abstract:
1. An electrode device for an electrochemical sensor chip for electrically connecting an analyte to electrodes formed on a surface of a transducer, comprising: an insulation sheet having an insulating property and including a top surface and a bottom surface facing opposite from each other; and electrode members having a conductivity and held by the insulation sheet in portions piercing the insulation sheet in thickness direction, one ends of the electrode members located on the top surface side of the insulation sheet being connected to the analyte, the other ends located on the bottom surface side of the insulation sheet being connected to the electrodes of the transducer, wherein at least the one ends of the electrode members to be connected to the analyte are made of a mixture of conductive particles and an insulating material, and wherein recesses for trapping an analyte are formed in the top surface of the insulation sheet so as to correspond to the electrode members, the recesses having a reversely tapered shape having a larger diameter at a bottom than at an opening that opens at the top surface of the insulation sheet, and the one ends of the electrode members are exposed at a bottom of the recesses.
