This paper proposes a new numerical model on tracer response analysis of a fractured geothermal reservoir. The multiple paths model has been generally used for analysis of tracer response. However, such a model is so complex that it has a lot of parameters to be determined. The model proposed in the paper has only one main path, composed of fracture and semi-fracture layers, and has fewer number of parameters to be specified than the multiple paths model does. The conclusions are as follows; (1) Good agreements are found between calculations by this model and observation data of tracer response in a geothermal reservoir. (2) It is possible to say that flow path in the reservoir is not always made up of multiple paths but of one main path composed of fracture and semi-fracture layers.
