To provide a filler pipe that prevents the generation of variation in wall thickness near a branch portion of a filler pipe body portion and a breather pipe, and is molded by a blow molding method.SOLUTION: In a filler pipe 1, a filler neck body portion 5, a branch portion 6, a filler pipe body portion 2, a breather pipe 3, and a connecting portion 4 are integrally formed by a blow molding method. The filler pipe body portion 2 has a generally straight filler pipe body vertical side part 7 coupled with one end portion of the connecting portion 4 on a cross-section. The breather pipe 3 has a generally straight breather pipe vertical side part 8 coupled to the other end portion of the connecting portion 4 on a cross-section. The branch portion 6, the filler pipe body portion 2 on a fuel tank side of the branch portion 6, the breather pipe 3, and the connecting portion 4 are formed inside an outline of the filler neck body portion 5 when viewed from the filler neck body portion 5 side.SELECTED DRAWING: Figure 3
