1. A biosensor, comprising:
- a working electrode disposed on a proximal end of the biosensor;
a counter electrode disposed on the proximal end of the biosensor;
a working electrode terminal disposed on a distal end of the biosensor;
a counter electrode terminal disposed on the distal end of the biosensor;
a first reference terminal disposed on the distal end of the biosensor;
a second reference terminal disposed on the distal end of the biosensor;
a first conductive line connecting the working electrode to the working electrode terminal;
a second conductive line connecting the working electrode to the first reference terminal;
a third conductive line connecting the counter electrode to the counter electrode terminal; and
a fourth conductive line connecting the counter electrode to the second reference terminal;
wherein;
the first conductive line and the second conductive line are disposed on one side of the biosensor relative to a centerline that extends between the proximal end and the distal end of the biosensor; and
the third conductive line and the fourth conductive line are disposed on the other side of the biosensor relative to the centerline.

Abstract
A biosensor includes a working electrode 101, a counter electrode 102 opposing the working electrode 101, a working electrode terminal 103 and a working electrode reference terminal 10 connected to the working electrode 101 by wires, and a counter electrode terminal 104 connected to the counter electrode 102 by a wire. By employing a structure with at least three electrodes, it is possible to assay a target substance without being influenced by the line resistance on the working electrode side.
