A ferrule for optical fiber connector includes a first body component, a second body component, and a third body component. The first body component includes at least one first mounting portion and two accommodation portions. The second body component is disposed above the first body component, and includes at least one second mounting portion, where the at least one second mounting portion corresponds to the at least one first mounting portion. The third body component is disposed above the first body component and the second body component, and includes at least one positioning through aperture and two second through apertures, where the two second through apertures correspond to the two accommodation portions, respectively. The first body component, the second body component, and the third body component are adhered integrally together, with adhesive. Also disclosed is a positioning mold for positioning the ferrule. By using the positioning mold, the ferrule for optical fiber connector can be assembled more easily, so as to improve the productivity in manufacturing optical fiber connectors.
