Abstract: Disclosed in the present invention is an oriented silicon steel, comprising, in addition to 90% or more of Fe and inevitable impurities, the following chemical elements in percentages by mass: C: 0.020-0.080%, Si: 2.00-4.50%, Mn: 0.01-0.10%, S ≤0.005%, acid-soluble Al: 0.010-0.040%, N: 0.002-0.015%, Nb: 0.006-0.120%, and at least one selected from P: 0.01-0.10%, Sn: 0.01-0.30%, and Cu: 0.01-0.50%. Further disclosed in the present invention is a manufacturing method for the oriented silicon steel, the method comprising: smelting and casting; heating; hot rolling; cold rolling; decarburization annealing; nitriding; coating of an annealing separant; high-temperature annealing; and coating of an insulating coating and scoring. The oriented silicon steel and the manufacturing method therefor of the present invention are environmentally friendly and low in terms of energy consumption, realize high-level matching between a high magnetic induction intensity and a low magnetostriction, and have very wide application prospects.
