PROBLEM TO BE SOLVED: To grasp the environmental condition of an apparatus. An environmental condition estimation device includes a challenge value input unit for inputting a challenge value toward a PUF circuit that outputs a unique response value according to a variation in the characteristics of a component element with respect to the input challenge value. It includes a response value acquisition unit that acquires a response value output from the PUF circuit, and an estimation unit that estimates the environmental conditions of the PUF circuit based on the response value.
