The invention discloses an annealed plate. The annealed plate comprises chemical components including, by mass percent, larger than 0% and smaller than or equal to 0.004% of C, larger than or equal to0.1% and smaller than or equal to 3.5% of Si, larger than or equal to 0.1% and smaller than or equal to 1.2% of Mn, larger than or equal to 0.1% and smaller than or equal to 1.0% of Al, larger than 0% and smaller than or equal to 0.01% of S, smaller than or equal to 0.004% of Ti, smaller than or equal to 0.003% of Nb, and the balance Fe and inevitable impurities. The invention further discloses aproduction method of the annealed plate. Through providing of the annealed plate and the production method of the annealed plate, the technical problems that in the prior art, an annealed plate is low in magnetic performance and instable in surface quality are solved, and the produced annealed plate is excellent in magnetic performance and mechanical performance and stable in surface quality.
