PROBLEM TO BE SOLVED: To provide a funnel that can much more rapidly transfer than conventional funnels, can easily transfer without placing a person's hand on the funnel, can use for a container such as a PET bottle having different pitches of screw threads, and can be easily attached and removed. SOLUTION: The funnel has a cross-sectional area of an outlet 4 for liquid that is 70% to 90% of the cross-sectional area of an inside diameter of a mouth of the container such as the PET bottle, and has an outlet 8 for air. A plurality of projections 6 or depressions are formed on the locations where the upper end face of the mouth of the container such as the PET bottle makes contact with the funnel, thereby forming the outlet 8 for air, and a plurality of nails 5 are projected so as to surround the outlet 4 for liquid and are accompanied by the periphery of the screw thread 7 of the container such as the PET bottle.
