To provide a manufacturing method of recycled fine aggregate which produces small amount of adhered materials except the aggregate ingredient such as mortar and the like and is capable of manufacturing recycled fine aggregate with high quality.

Concrete masses B generated at a construction site and the like are formed into the crushed concrete V which is produced by a jaw crusher 3. The crushed concrete V is polished by an ore polishing machine 10 at a first ore polishing step and classified by a vibration sieve 8. The crushed material S2 substantially corresponding to sand and crushed material S3 corresponding to fine aggregate, which have been crushed by the vibration sieve 8, are polished in the presence of a polish treatment stone 61 by the ore polishing machine 11 at a second ore polishing step after mixing at a predetermined ratio. Thus, the mortar moiety M which has been adhered to the surface of the fine aggregate ingredient is removed and the recycled fine aggregate N in which the amount of the adhered mortar moiety M is small is obtained.
