To provide a continuous manufacturing method and an apparatus for a galvanized sheet for securing uniformity of coating weight in the width direction.

In this continuous manufacturing method for galvanized sheet, a steel sheet is continuously dipped into a plating bath, and the steel sheet with molten zinc adhered thereto is led upward by a sink roll in the plating bath and drawn upward of the plating bath to continuously perform hot-dipping of the steel sheet. Molten zinc is blown to both sides of the steel sheet in the plating bath passing the sink roll in the plating bath, and magnetic force is applied by a non-contacting type magnetism application means to both sides of steel sheet drawn up from the plating bath to correct warp of the steel sheet in the width direction.
