SOLUTION: This detection device has a specimen holding part for holding a material 8, irradiation means 1, 6, detection means 1, 7, a calculation means and an evaluation means. The irradiation means 1, 6 irradiate the terahertz wave to the material 8 held by the specimen holding part.

The calculation means determines frequency dependence of a property of the material 8 to the irradiated terahertz wave, and calculates a slope of a straight line or a slope of a straight line obtained by straight-line approximation of the frequency dependence of the property of the material 8. The evaluation unit evaluates the state change of the material by comparing a previously-obtained slope of a straight line of the frequency dependence of the property of the material in a standard state with the slope of the straight line of the material 8 calculated by the calculation means.
