To provide an oriented electromagnetic steel sheet in which a plurality of grooves extending in sheet width direction are formed in sheet length direction at predetermined intervals, a wound iron core formed by winding the oriented electromagnetic steel sheet, and production methods for the oriented electromagnetic steel sheet and the wound iron core.SOLUTION: The present invention provides an oriented electromagnetic steel sheet in which a plurality of grooves extending in sheet width direction are formed in sheet length direction at predetermined intervals. It has a sheet width for winding of a wound iron core, and non-grooved parts are formed in any region excluding a sheet width end in the sheet width direction, and a region excluding the non-grooved parts in the sheet width direction has the grooves formed thereon.SELECTED DRAWING: Figure 2
