To manufacture a winding body which can avoid the damage of other components or the like caused by a terminal end part of a metal wire rod by shortening a distance from a weld part to a terminal end edge as much as possible without increasing the number of manufacturing steps, thereby preventing a defective winding body from being manufactured.SOLUTION: There is provided a porous winding body (filter 10) to which at least one continued metal wire rod 20 is spirally wound in a multi-layered state. In the winding body, a terminal end part 30 (metal wire rod portion 20n) of the metal wire rod is resistance spot-welded to the other portion (metal wire rod portion 20m) of the metal wire rod, and fused at the welded point. The terminal end part 30 (metal wire rod portion 20n) has a weld-solidified part 31n which is solidified after the metal wire rod in a width direction is entirely welded.SELECTED DRAWING: Figure 2

    【課題】製造工程数を増加させることなく、溶接部から終端縁までの距離をできるだけ短くして、金属線材の終端部によって他部品等を損傷させない巻線体を製造し、欠陥のある巻線体が製造されないようにする。【解決手段】少なくとも1本の連続する金属線材20が螺旋状且つ多層状に巻きつけられた多孔の巻線体(フィルタ10)である。巻線体において、金属線材の終端部30(金属線材部分20n)は、金属線材の他の部分(金属線材部分20m)に抵抗スポット溶接されると共に、該溶接された箇所において溶断されている。終端部30(金属線材部分20n)は、金属線材の幅方向の全体が溶融した後に凝固した溶融凝固部31nを有する。【選択図】図2
