The invention relates to non-oriented electrical steel and a production method thereof. The non-oriented electrical steel comprises the following chemical compositions in percentage by weight: less than or equal to 0.008 percent of C, 0.15 to 2.2 percent of Si, less than or equal to 0.008 percent of Al, 0.15 to 1.5 percent of Mn, 0.004 to 0.15 percent of P, less than or equal to 0.008 percent of S, less than or equal to 40PPm of [O], less than or equal to 0.005 percent of N, less than or equal to 0.008 percent of Ti, and the balance of iron and inevitable impurities. The production method comprises the following steps of: smelting by using a converter and performing vacuum treatment; continuously casting into slabs with the thickness of 50-90 millimeters; soaking in a tunnel kiln; continuously rolling by using seven mills; coiling; performing pickling; performing cold rolling; performing recrystallization annealing; and obtaining the steel for later use. The alloy is reasonable in design and is not needed to be subjected to calcium treatment; the procedures are simple; the cost is reduced; the defect of low casting property in thin slab continuous casting-continuous rolling production can be effectively overcome; the advantages on cost and magnetic property of the non-oriented electrical steel in the thin slab continuous casting-continuous rolling production are fully shown, and the market competitiveness of the product is greatly improved.
