Lorsque la quantité de charge pour 100 parties en masse de résine polyarylène sulphide est représentée par x, et que la la viscosité à l'état fondu (Pa.s) mesurée à 310°C et à une vitesse de cisaillement de １２１６ｓｅｃ－１ de la résine polyarylène sulphide, est représentée par y, alors x et y satisfont la formule (1). ｙ≦－１,０８７ｘ＋２１６,９６ （１）
