PROBLEM TO BE SOLVED: To provide a method for manufacturing a steel material of improved quality with non-magnetically modified phase. SOLUTION: The method for manufacturing the steel material with non-magnetically modified phase includes: forming a space 20 inside by stacking a plurality of steel materials 1; putting a modified metal 3 into the space 20; energizing and pressurizing the stacked steel materials 1 using a pair of electrodes 5 interposed in a stacking direction at a location of the modified metal 3, and melting the modified metal 3 together with a part of the surrounding steel materials 1 to form the non-magnetically modified phase. In this method, the steel material includes the modified metal 3 which is larger in a direction of being pressurized by the electrodes 5 than the space 20. COPYRIGHT: (C)2011,JPO&INPIT
