PROBLEM TO BE SOLVED: To provide an axial flow pump capable of inhibiting cavitation and leak flow while maintaining pump head. SOLUTION: In a plurality of moving blades 5 attached on a pump shaft 3 with inclined to a circumference direction from an upstream side to a downstream side, a section 5FL in a radial direction of a moving blade leading edge 5F which is in a rotary direction front side is formed in a convex shape toward the upstream side and a section 5RT in a radial direction of a moving blade trailing edge 5R which is in a rotary direction rear side is formed in a convex shape toward the downstream side.
