Patent ID: 8648605

Claim:
A sensor comprising: first and second conductive electrodes; first and second conductive wiring lines that are respectively connected to the first and second conductive electrodes, wherein the first and second wiring lines are connected to corresponding connection terminals; an insulating portion that insulates the first wiring line from the second wiring line and insulates the first and second wiring lines from a liquid including an analyte, wherein the insulating portion is made of an organic material, and at least the surfaces of portions of the first and second electrodes that come into contact with the liquid including the analyte are made of a material that is insoluble by the liquid including the analyte; an insulating substrate that is made of an organic material; at east one electrode group that includes the first and second electrodes and is arranged on the insulating substrate; at least one connection wiring line group that is electrical connected to the at least one electrode group and has at least one layer including the first and second wiring lines; at least one connection terminal group that is electrically connected to the at least one connection wiring line group; and at least a coverlay that is provided on the insulating substrate, has openings through which the at least one electrode group is exposed to the outside, and covers the at least one connection wiring line group, wherein at least the coverlay and the insulating substrate form the insulating portion that insulates the at least one connection wiring line group and insulates the conductive wiring lines from the liquid including the analyte.
