Cortisol is conventionally known as a stress marker, but there are cases in which the expression thereof during stress is not constant, so cortisol is an unstable indicator. Further, cortisol does not enable distinguishing between acute stress and chronic stress. This stress evaluation method is characterized in that a state of acute stress in the test subject is determined when the 1,2,3,4-tetrahydrocyclopenta[b]indole shown in expression (1) is expressed.
