Zusammenfassung:	PURPOSE: To mold a filter effectively minimized in contamination of a synthetic resin filter by a method wherein a synthetic resin is injected around a top component and a bottom component of the synthetic resin made filter to mold integrally the synthetic resin made filter. CONSTITUTION: A synthetic resin made filter component 1 and its bottom component 2 are independently molded by injection in a mold 11. The mold 11 is opened, the synthetic resin made filter top component 1 and its bottom component 2 are held on a mold component 13, at least one side is moved, and besides a filter film 10 is placed on either of the synthetic resin made filter top component 1 or the synthetic resin made filter bottom component 2. The synthetic resin made filter top component 1 and the bottom component 2 wherein the filter film 10 is held thereby on the mold component by putting that between them, are superimposed on each other, and the mold 11 is closed. Then, synthetic resin is injected around the synthetic resin made filter top component 1 and the bottom component 2. The synthetic resin made filter is integrally molded thereby.
