1. A pellet production method comprising:
an operation in which a strand comprising a glass-fiber-reinforced polyamide resin composition containing 50 mass % to 80 mass % of glass fiber is extruded from an orifice at a die;
an operation in which the strand is drawn into water within a tank and is cooled; and
an operation in which the cooled strand is cut to obtain a pellet;
wherein an angle of incidence at which the strand enters the water within the tank is not less than 70° but is less than 90°; and
wherein a ratio of a diameter of the pellet to a diameter of the orifice (diameter of the pellet/diameter of the orifice) is 0.65 to 0.97.
