PROBLEM TO BE SOLVED: To provide a fuel pump module which is able to be compacted and to cope with unexpected breakage at a low cost. SOLUTION: A fuel pump module 1 comprises a pumping function part 2 which has only a pumping function for sucking fuel existing in a reservoir, a filter 11 connected to the pumping function part 2 via a first fuel passage 41, a backflow preventing function part 3 mounted on the first fuel passage 41 to prevent a backflow of the fuel flowing through the first fuel passage 41, a second fuel passage for introducing the fuel from the filter 11 to the engine, and a pressure regulating function part 4 for maintaining fuel pressure in the second fuel passage, wherein the pumping function part 2, the backflow preventing function part 3, and a pressure regulating function part 4 are separated for each single function, and then are integrated together.
