Abstract: An adsorption evaluation apparatus includes a measurement unit and an evaluation unit. The measurement unit irradiates a porous framework being an evaluation object with a terahertz wave, and performs measurement of a refractive index or a real part of a complex permittivity of the porous framework based on the terahertz wave which interacted with the porous framework. The evaluation unit performs evaluation of adsorption of a substance on the porous framework based on the refractive index or the real part of the complex permittivity of the porous framework measured by the measurement unit.
