PURPOSE:To mix up many ingredients effectively with one another, by a method wherein a mixing part for a main ingredient is formed on one side of a split mold and an introduction path communicating a secondary mixing part possessing an inflow port for a primary mixing ingredient and a casting port for an auxiliary ingredient and a mixing part with a molding cavity is formed after a split surface of a mold. CONSTITUTION:A resin ingredient is cast into a mixing chamber 31 of a primary mixing part 30 through casting ports 22, 23, mixing of a main ingredient is performed and flows into a secondary mixing part 30 through an inflow port 29. An auxiliary ingredient is cast into the mixing chamber 31 through casting ports 32, 33 of the mixing chamber 31, mixed into a first mixing ingredient and then secondary mixing is performed, in the mixing chamber 31 of the secon dary mixing part 30. A secondary mixture ingredient composed of the main ingredient and auxiliary ingredient mixed up with each other hereupon is intro duced into a mold cavity 10 through an introduction path 40. After molding the mixture ingredient remaining into the introduction path communicating the secondary mixing part 30 and mixing part with a mold cavity is removed along with a molded product at the time of mold break of a mold.
