摘要：
An object of the present invention is to make a joined portion of a metal wire less likely to catch on other components and the like. A hollow cylindrical filter 200 is formed by winding one or a plurality of metal wires 220 in a helical and multilayered manner so that metal wire portions adjacent to each other in a direction toward an inner or outer diameter side extend in directions crossing each other. The filter includes a deformed joining part 231 including a first metal wire portion 220A having been pressed and deformed and a second metal wire portion 220B having been pressed and deformed via the first metal wire portion and joined to the first metal wire portion by resistance spot welding, where the deformed joining part penetrates into a communication space positioned at an inner side of the deformed joining part. Since the metal wire is pressed and deformed at the deformed joining part, the deformed joining part is less likely to catch on other components and the like during handling of the filter.
