Abstract: The electrolyte analysis test strip of the present invention includes a substrate extending in one direction. A first ion-sensitive film provided in a specific region on the one end side in the one direction and a first extraction electrode extending from the first ion-sensitive film to the other end side are provided on one main surface of the substrate. A second ion-sensitive film provided in a specific region on the one end side and a second extraction electrode extending from the second ion-sensitive film to the other end side are provided on the other main surface of the substrate. The first ion-sensitive film and the second ion-sensitive film each come into contact with an electrolyte to generate a first potential corresponding to a concentration of a first ion species and a second potential corresponding to a concentration of a second ion species, respectively.

Abstract: The present invention provides an electrolyte analysis test strip for measuring a concentration of ions contained in an electrolyte. The electrolyte analysis test strip includes a substrate extending in one direction. An ion sensitive electrode is provided in specific regions on a side of one end in the one direction on a main surface of the substrate. A main extraction electrode extends from the ion sensitive electrode to a side of an other end. A solution detection electrode is provided in a proximal region in a manner separated from the main extraction electrode, and is for detecting whether or not the solution detection electrode is in contact with the electrolyte. An auxiliary extraction electrode extends from the solution detection electrode to the side of the other end in a manner separated from the main extraction electrode.

Abstract: A test strip for biological component measurement includes a substrate. A pair of a working electrode and a counter electrode, a sensor unit that produces an electrochemical reaction with a bodily fluid of a measurement subject and produces a change in electrical characteristics, a resistance portion having an electrical resistance expressing attribute information including a sensitivity of the test strip, and a pair of wires connected to both ends of the resistance portion are provided on the substrate. The resistance portion has a plurality of narrow patterns, each having a resistivity and provided so as to be distanced from each other. An end portion of each narrow pattern is near another narrow pattern. A substantially circular pattern is provided to overlap locations where the end portions of the narrow patterns are near each other, enabling the end portions to conduct with each other.
