PROBLEM TO BE SOLVED: To provide an indicator device with which inhibition of enzymatic reaction is hard to occur and temperature hysteresis can be monitored with desired timing. SOLUTION: The indicator device is provided on an external surface or the inside of a storage container for storing a target, and is equipped with: an oxidizing enzyme; a matrix of the oxidizing enzyme; and an enzymatic reaction part storing the oxidizing enzyme and the matrix inside and equipped with an oxygen permeable oxygen transmitting means. Deviation from a normal storage temperature of the target is detected by a degree of a reaction product generated by advancing the enzymatic reaction between the oxidizing enzyme and the matrix in the presence of oxygen.
