    • PROBLEM TO BE SOLVED: To provide a manufacturing method of a mandrel and its apparatus manufacturing the mandrel constantly with a given outer diameter without exchanging a sizing die with a die of different size, even if a temperature condition of the manufacturing site varies. SOLUTION: Variation of the outer diameter of the mandrel 1 can be suppressed by controlling the temperature of the sizing die 20 by oil of an oil passage 23, by molding molten resin 2 by the sizing die 20 while passing oil of given temperature through the oil passage 23 provided in the sizing die 20. Thus, the mandrel 1 can be constantly manufactured with a given outer diameter without exchanging the sizing die 20 with a die of different size, even if the temperature condition of the manufacturing site varies.
