PROBLEM TO BE SOLVED: To provide a pump part which comprises a polyphenylene ether-based resin composition and has improved mold-processability, mechanical strength and vibration fatigue characteristics. SOLUTION: This pump part is formed from a polyphenylene ether-based resin composition which comprises 5 to 95 pts.mass of a polyphenylene ether copolymer (A) polymerized from 5 to 70 mass% of 2,3,6-trimethylphenol and 95 to 30 mass% of 2,6-dimethylphenol, 0 to 90 pts.mass of a styrenic resin (B), and 5 to 60 pts.mass of an inorganic filler (C) surface-treated with a silane compound.
