Zusammenfassung:	무방향성 전기강판 및 그 제조방법이 제공된다 본 발명의 전기강판은, 중량%로, C: 0.005% 이하, Si: 2.5~4.5%, Mn: 0.1~2.5%, P: 0.002~0.02%, S: 0.001~0.005%, Al: 0.5~2.5%, N:0.005% 이하, Ti: 0.005% 이하, 잔부 Fe 및 불가피한 불순물을 포함하고, Al, Si 및 Mn이 소정의 관계식 1을 만족하고, 강판의 집합조직이 관계식 3을 만족하도록 형성되어 있다. Provided are a non-oriented electrical steel sheet and a manufacturing method therefor. The electrical steel sheet of the present invention comprises, by weight%, C: 0.0050% or less, Si: 2.50 to 4.50%, Mn: 0.10 to 2.50%, P: 0.002 to 0.020%, S: 0.0010 to 0.0050%, Al: 0.50 to 2.50%, N: 0.0050% or less, and Ti: 0.0050% or less, the balance being Fe and inevitable impurities, wherein Al, Si, and Mn satisfy relation expression 1, and the steel sheet's texture is formed to satisfy relation formula 3.
