Zusammenfassung:	A grain-oriented electrical steel sheet, according to one embodiment of the present invention, comprises: linear grooves formed on one surface or both surfaces of the electrical steel sheet in the direction (X1 direction) crossing a rolling direction; and punctuated grooves formed on one surface or both surfaces of the electrical steel sheet so as to be arranged in the direction (X2 direction) crossing the rolling direction, wherein the plurality of linear grooves and the plurality of punctuated grooves are formed in the rolling direction, and an interval (D3) between the punctuated grooves with respect to an arrangement direction (X2 direction) of the punctuated grooves is 0.02 to 1.7 times the interval (D2) between the punctuated grooves with respect to the rolling direction. Une tôle d'acier magnétique à grains orientés, selon un mode de réalisation de la présente invention, comprend : des rainures linéaires formées sur une surface ou sur les deux surfaces de la tôle d'acier magnétique dans la direction (direction X1) croisant une direction de laminage ; et des rainures ponctuelles formées sur une surface ou sur les deux surfaces de la tôle d'acier magnétique de façon à être agencées dans la direction (direction X2) croisant la direction de laminage, la pluralité de rainures linéaires et la pluralité de rainures ponctuelles étant formées dans la direction de laminage, et un intervalle (D3) entre les rainures ponctuelles par rapport à une direction d'agencement (direction X2) des rainures ponctuelles étant de 0,02 à 1,7 fois l'intervalle (D2) entre les rainures ponctuelles par rapport à la direction de laminage. 본 발명의 일 실시예에 의한 방향성 전기강판은 전기강판의 일면 또는 양면에, 압연방향과 교차하는 방향(X1 방향)으로 형성된 선상의 그루브; 및 전기강판의 일면 또는 양면에, 압연방향과 교차하는 방향(X2 방향)으로 배열되어 형성된 점상의 그루브를 포함하고, 선상의 그루브 및 점상의 그루브는 압연방향을 따라 복수개 형성되고, 점상의 그루브 배열 방향(X2 방향)에 대한 점상의 그루브 간의 간격(D3)은 압연방향에 대한 점상의 그루브 간의 간격(D2)의 0.02 내지 1.7배이다.
