A manufacturing method for a grain-oriented electrical steel sheet according to an embodiment of the present invention comprises the steps of: preparing a cold-rolled plate; irradiating the cold-rolled plate with a laser to form grooves; removing Fe-O oxide formed on the surface of the cold-rolled plate; subjecting the cold-rolled plate to primary recrystallization annealing; and applying an annealing separator to the primarily recrystallized cold-rolled plate, followed by secondary recrystallization annealing, wherein the grain-oriented electrical steel sheet has a fit factor of 0.016-1.13 as calculated by equation 1 below. [Equation 1] Fit factor (Sad) = (0.8×R)/Hhill-up (In equation 1, R represents the average roughness (㎛) of the surface of the cold-rolled plate after the step of removing the oxide; and Hhill-up represents the average height (㎛) of hill-ups present on the surface of the cold-rolled plate after the step of removing the oxide.) ...
