PROBLEM TO BE SOLVED: To provide a compact funnel which can be set at a mouth part of a container and through which a container can be refilled with a liquid even by one person and can be easily stored. SOLUTION: The funnel 1 includes an out flow pipe 4 to be inserted into a mouth part 3 of a container 2 and a funnel body 6 which is provided at the upper part of the pipe 4 and of which the upper part is opened. An outer leg part 7, which surrounds the pipe 4 in a concentric manner, spaced apart from the pipe 4, extends downward from the lower part of the body 6. Hence even if the pipe 4 inserted into the mouth part 3 of the container 2 is inclined, the pipe 4 or the leg part 7 is prevented from slipping out of the mouth part 3 (where D1 is the diameter of the part 7, D2 is the diameter of the pipe 4, d is difference in radius between the part 7 and pipe 4, F is the length of the part 7). The lower end 7a of the part 7 is located at a level slightly lower than the lower end 4a of the pipe 4.
