PURPOSE:To provide the manufacture of a cylindrical baked composite body, in which no defect such as crack is generated and which has excellent productivity. CONSTITUTION:An internal resin section 1 is installed inside a cylindrical sintered article 2, and used as the rotor of a magnetic sensor in the manufacture of a cylindrical sintered composite body, an idle resin section 3 is molded on the outside before the internal resin section 1 is molded inside the cylindrical sintered article 2 composed of iron oxide, and the idle resin section 3 is removed. A resin feed rate at a time when the idle resin section 3 is molded is made larger than that at a time when the internal resin section 1 is molded. Both resin feed rates can also be equalized. The quantity of a resin fed to the inside is made the same as or larger than that fed to the outside at that time. |
