PROBLEM TO BE SOLVED: To provide a resinified pump device and a manufacturing method suitable for a resin component for such a pump, for reducing weight, and improving corrosion resistance, by resinifying in a state of being superior in productivity, with sufficient strength, even in a component requiring high strength such as an impeller. SOLUTION: In this manufacturing method of the resin component for the pump device, the resin component for the pump device such as the impeller 4 is made by the manufacturing method comprising a preliminary process (a) of sealing a reinforced fiber material 10 in a mold 11, a resin injection process (b) of sucking and injecting a synthetic resin into the mold 11 in a fluid state by putting the inside of the mold 11 sealed with the reinforced fiber material 10 under negative pressure, and a hardening process (c) of hardening resin injected into the mold 11.
