To provide a coil filter which has the shape holding property similar to a conventional technique even though thermal processing is not applied thereto, and can be easily manufactured.SOLUTION: There is provided a coil filter which is formed into a cylindrical body having a stitch by superimposing metal wire materials 91 forming a plurality of layers on each other in the radial direction, in which a terminal part (adhesive part 93) of the metal wire material 91 on the outermost layer in the plurality of layers is joined by being bonded to at least a portion of a layer adjacent on the radial direction inner side to the outermost layer, by being drawn to the inner surface side via one axial direction end to be bonded to at least a portion of the innermost layer, or by being bonded to a portion of the one axial direction end, and the joint strength of the terminal part (adhesive part 93) of the metal wire material 91 on the outermost layer is equal to or greater than 5 N.SELECTED DRAWING: Figure 3

    【課題】熱処理されていなくても、従来と同様の形状保持性を備えつつ、さらに容易に製造できる巻線フィルタを提供する。【解決手段】径方向へ複数層をなす金属線材91同士が重なり合って編目を有する筒状体に形成された巻線フィルタであって、複数層のうち最外層の金属線材91の終端部(接着部93)が、最外層に対して少なくとも径方向内側で隣接する層の一部に接着されること、いずれか一方の軸方向端部を介して内面側に引き込まれ、少なくとも最内層の一部に接着されること、または、いずれか一方の軸方向端部の一部に接着されること、によって接合しており、最外層の金属線材91の終端部(接着部93)の接合強度が5N以上であることを特徴とする。【選択図】図3
