PROBLEM TO BE SOLVED: To provide a test piece for biogenic substance measurement to which body fluid of a subject is adhered so as to measure concentration of a specific component contained in the body fluid and which can be inexpensively manufactured with high quality.SOLUTION: The test piece for biogenic substance measurement includes a substrate 11 on which there are provided a pair of a working electrode 12 and a counter electrode 13, a sensor part 15 whose electrical property is changed by an electrochemical reaction with body fluid of a subject, a resistance part 14 having electrical resistance representing attribute information including sensitivity of the test piece, and a pair of wiring 42, 43 connected to ends of the resistance part 14. The resistance part 14 has a plurality of elongated patterns 44, 45, 46, 47 spaced apart from each other, each having a certain resistivity. An end of each elongated pattern is located close to ends of other elongated patterns. The resistance part 14 also has substantially round circular patterns 71 which overlap proximate ends of the elongated patterns to electrically connect the proximate ends. |
