It is an object of this invention to provide a stress assessment device capable of assessing mental stress without requiring another previous knowledge or imposing a load on an observer or an employee. A stress assessment device (10) of this invention includes: a work behavior acquisition unit (101) for acquiring a work behavior time-series pattern serving as information indicating a work behavior of each employee in temporal units; an eigen-behavior time-series pattern calculation unit (102) for calculating an eigen-behavior time-series pattern serving as information indicating a standard work behavior of each employee by using the work behavior time-series pattern; and a stress state assessment unit (103) for calculating a reconstruction accuracy indicating a degree to which the work behavior time-series pattern of each employee and the eigen-behavior time-series pattern agree with each other and assessing a stress state of the employee based on the calculated reconstruction accuracy.
