PROBLEM TO BE SOLVED: To provide an organic Rankine cycle system capable of easily and safely handling a working fluid even if an organic medium is used.SOLUTION: An organic Rankine cycle system includes: a heat exchanger causing heat exchange between a heat source and a working fluid to heat the working fluid, the working fluid being a substance dissolved in a solvent; an expansion mechanism to which the working fluid heated in the heat exchanger is supplied, and that expands the working fluid; a condenser that cools the working fluid passing through the expansion mechanism to change the working fluid to a liquid working fluid; a liquid supply pump that pressurizes the working fluid supplied from the condenser, and that supplies the pressurized working fluid to the heat exchanger; a circulation path in which the working fluid and steam circulate by connecting the heat exchanger, the expansion mechanism, the condenser, and the liquid supply pump; a working-fluid supply mechanism connected to the circulation path, and supplying a liquid mixture that is a mixture of the working fluid and the solvent to the circulation path; a solvent trap arranged in the circulation path, and separating the working fluid from the solvent; a solvent collection mechanism collecting the solvent separated by the solvent trap; and a control device.
