PROBLEM TO BE SOLVED: To provide a line filter small in size and easy to produce by facilitating a resin casting work for fixing a coil to a case whose packaging area is reduce, eliminating an excessive space on the lower part of a terminal table and further forming a core smaller than a magnetic path cross-sectional area required for conventional materials. SOLUTION: At attaching hole part is provided inside the case or in a recessed part thereon, notches are provided on the upper central parts of left and right side walls, and a resin case partitioned by two partition walls is molded on a metal bottom palate. Then, a coil is fixed on the central part of this case by a resin, a relay terminal board to which an external terminal is connected is fixed to both the terminals of the coil partitioned by the partition walls by connecting a composite capacitor located on the lower part by using a resin, and the line filter is configured by being covered with an attachable and detachable lid case provided with an air hole and an input/output cable lead-in groove. Besides, a core, on which the thin band of amorphous hyperfine crystal alloy is wound, is used.
