摘要： PROBLEM TO BE SOLVED: To extremely shorten the manufacturing time by forming manganese zinc system ferrite into the shape of a core and then burning it in a burning atmosphere with its oxygen concentration controlled by a carbon dioxide gas and steam and then cooling it at a specified cooling speed. SOLUTION: A main ingredient consisting of 50 mol% or above of Fe2O3, MnO, ZnO and 0.04 to 0.6 wt.% of CaO as a sub ingredient are mixed, provisionarily burned, ground into powder and then dried to form a core. This molded body is sintered. The burning atmosphere, that is, an atmosphere at the time of sintering, is preferably one including 5 to 21% of oxygen. The concentration of oxygen in this atmosphere is controlled by using the air, a carbon dioxide gas, and steam. Thereafter, the decrease in temperature from the sintering temperature, that is, cooling is conducted at 250 to 850 deg.C/hour, preferably a rapid cooling at 300 to 850 deg.C/hour.
