Abstract
A mesh hook surface fastener does not lose engagement ability even when subjected to mold-in forming and gives only a slight feeling of something foreign. The mesh hook surface fastener contains first shape holding ribs (a) with a relatively small protrusion height and second shape holding ribs (a) with a relatively large protrusion height which protrude to the opposite side of hook-shaped engagement elements (B, B) across a base layer (A) and are alternately arranged. The heights of the adjacent shape holding ribs (a, a) are different, which prevents the direct entrance of a foamable resin liquid and weakens its force. As the force weakens, foaming and curing progress more readily and, as a result, the amount of the foamable resin liquid that passes through meshes of the base layer to reach the hook-shaped engagement elements can be reduced.
