<P>PROBLEM TO BE SOLVED: To provide a three phase linear type electromagnetic stirring device in which the capacity of a three phase AC power source is decreased, and the distribution of the stirring force in the longitudinal direction of a linear type iron core is uniformed. Ž<P>SOLUTION: The electromagnetic stirring device 10 has, in the molten steels subjected to continuous casting, a plurality of magnetic poles 13 arranged in parallel, linear type iron cores 14, 15 arranged so as to be confronted, coils of a U phase, a V phase and a W phase coiled around the linear type iron cores 14, 15, and a three phase AC power source with variable frequency feeding three phase electric current to the coil of each phase. The number of turns N<SB>o</SB>of unit coils 16, 19, 22 and 25 at the edge parts respectively arranged at both the edge sides of the linear type iron cores 14, 15 is made larger than the number of turns N<SB>I</SB>of the remaining unit coils 17, 18, 20, 21, 23, 24, 26, 27, and the uniformization of the electric current flowing through the coils of the U phase, the V phase and the W phase is achieved.
