    摘要： Provided are a sensor chip which permits deterioration status of an agent applied on a reacting section of the sensor chip to be detected at the time of measuring concentration of a material to be measured, and a sensor system which can perform accurate measurement while detecting the deterioration status of the agent by using such sensor chip. In the sensor chip, two substrates facing each other and a spacer layer between the substrates are provided, a plurality of reacting sections are provided in the spacer layer, and on the surface of the substrate on the spacer layer side, an electrode system for detection is arranged to expose in the reacting section. The sensor chip is characterized in that the same agent (A) is applied on two or more reacting sections among the reacting sections, and furthermore, on at least one reacting section of the two or more reacting sections, another agent (B) which reacts with the agent (A) is applied. The sensor system is characterized in that the system is provided with a measuring means which compares current values from the sensor chip and each of the two or more reacting sections.
