摘要： A web support with a high degree of patterning freedom and excellent durability, a production method therefor, and a patterning method. The web support is used when applying a pattern to a nonwoven substance by jetting a high-pressure water stream on a web. The web support production method comprises: a step of preparing a flat metal base material; a step for forming, by etching, a first water conduction hole and second water conduction hole that pass through the front surface of the base material to the back surface, and a recess on the front surface of the base material that includes the first water conduction hole and that corresponds to the pattern; and a step for forming the base material into a cylindrical main body section by welding the edges of the base material to each other.
