Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an easy-to-use sensor and a sensor chip equipped with the sensor. SOLUTION: This sensor 10 includes an enzyme selectively reacting with a detecting object substance, pigment changing its color based on a reaction between the object substance and the enzyme, and a gel 13 holding the enzyme and the pigment. The sensor allows to determine whether or not the object substance is detected by means of change in color of the sensor, and the sensor is easy-to-use since it is formed of the gel being nonbreakable because of its low brittleness. A user can determine whether the object substance is contained in a specimen by visually observing the change in color of the sensor 10 (or by using an instrument such as a spectrophotometer) while contacting the sensor 10 with the specimen (gaseous specimen or liquid specimen).
